Runs an asynchronous DevToolsProtocol method. For more information

DevTools Protocol Viewer
. The methodName parameter is the full name of the method in the
{domain}.{method} format. The parametersAsJson parameter is a JSON
formatted string containing the parameters for the corresponding method.
The Invoke method of the handler is run when the method
asynchronously completes. Invoke is run with the return object of the
method as a JSON string. This function returns E_INVALIDARG if the methodName is
unknown or the parametersAsJson has an error. In the case of such an error, the
returnObjectAsJson parameter of the handler will include information
about the error.
Note even though WebView2 dispatches the CDP messages in the order called,
CDP method calls may be processed out of order.
If you require CDP methods to run in a particular order, you should wait
for the previous method's completed handler to run before calling the
next method.
