This defaults to `then`, `toJSON`, `Symbol.toString`, and `Symbol.toPrimitive`. You can add other properties to specify that they should be run locally on the javascript host object proxy.
  /// `log` | This is a callback that will be called with debug information. For example, you can set this to `console.log.bind(console)` to have it print debug information to the console to help when troubleshooting host object usage. By default this is null.
  /// `shouldSerializeDates` | By default this is false, and javascript Date objects will be sent to host objects as a string using `JSON.stringify`. You can set this property to true to have Date objects properly serialize as a `VT_DATE` when sending to the native host object, and have `VT_DATE` properties and return values create a javascript Date object.
  /// `defaultSyncProxy` | When calling a method on a synchronous proxy, the result should also be a synchronous proxy. But in some cases, the sync/async context is lost (for example, when providing to native code a reference to a function, and then calling that function in native code). In these cases, the proxy will be asynchronous, unless this property is set.
  /// `forceAsyncMethodMatches ` | This is an array of regular expressions. When calling a method on a synchronous proxy, the method call will be performed asynchronously if the method name matches a string or regular expression in this array. Setting this value to `Async` will make any method that ends with Async be an asynchronous method call. If an async method doesn't match here and isn't forced to be asynchronous, the method will be invoked synchronously, blocking execution of the calling JavaScript and then returning the resolution of the promise, rather than returning a promise.
  /// `ignoreMemberNotFoundError` | By default, an exception is thrown when attempting to get the value of a proxy property that doesn't exist on the corresponding native class. Setting this property to `true` switches the behavior to match Chakra WinRT projection (and general JavaScript) behavior of returning `undefined` with no error.
  ///
  /// Host object proxies additionally have the following methods which run
  /// locally.
  ///
  /// Method name | Details
  /// ---|---
  ///`applyHostFunction`, `getHostProperty`, `setHostProperty` | Perform a method invocation, property get, or property set on the host object. Use the methods to explicitly force a method or property to run remotely if a conflicting local method or property exists.  For instance, `proxy.toString()` runs the local `toString` method on the proxy object. But proxy.applyHostFunction('toString') runs `toString` on the host proxied object instead.
  ///`getLocalProperty`, `setLocalProperty` | Perform property get, or property set locally.  Use the methods to force getting or setting a property on the host object proxy rather than on the host object it represents. For instance, `proxy.unknownProperty` gets the property named `unknownProperty` from the host proxied object.  But proxy.getLocalProperty('unknownProperty') gets the value of the property `unknownProperty` on the proxy object.
  ///`sync` | Asynchronous host object proxies expose a sync method which returns a promise for a synchronous host object proxy for the same host object.  For example, `chrome.webview.hostObjects.sample.methodCall()` returns an asynchronous host object proxy.  Use the `sync` method to obtain a synchronous host object proxy instead: `const syncProxy = await chrome.webview.hostObjects.sample.methodCall().sync()`.
  ///`async` | Synchronous host object proxies expose an async method which blocks and returns an asynchronous host object proxy for the same host object.  For example, `chrome.webview.hostObjects.sync.sample.methodCall()` returns a synchronous host object proxy.  Running the `async` method on this blocks and then returns an asynchronous host object proxy for the same host object: `const asyncProxy = chrome.webview.hostObjects.sync.sample.methodCall().async()`.
  ///`then` | Asynchronous host object proxies have a `then` method.  Allows proxies to be awaitable.  `then` returns a promise that resolves with a representation of the host object.  If the proxy represents a JavaScript literal, a copy of that is returned locally.  If the proxy represents a function, a non-awaitable proxy is returned.  If the proxy represents a JavaScript object with a mix of literal properties and function properties, the a copy of the object is returned with some properties as host object proxies.
  ///
  /// All other property and method invocations (other than the above Remote
  /// object proxy methods, `forceLocalProperties` list, and properties on
  /// Function and Object prototypes) are run remotely.  Asynchronous host
  /// object proxies return a promise representing asynchronous completion of

  /// resolves after the remote operations complete and the promises resolve to
  ///  the resulting value of the operation.  Synchronous host object proxies
  /// work similarly, but block running JavaScript and wait for the remote
