Notice
You can set the Unity SDK to handle Airbridge related tasks occurring on the in-app website in hybrid apps without changing the website code.
Unity SDK can handle commands related to event transmission, device settings, and user settings that take place in the Web SDK. Set up using Airbridge.CreateWebInterfaceScript and Airbridge.HandleWebInterfaceCommand functions before displaying the website in the web view.
webToken is a Web SDK token. The Web SDK token can be checked in Airbridge dashboard under [Settings]>[Tokens].
postMessageScript is a JavaScript code that delivers the payload variable, which stores the command passed from the web SDK to the Unity SDK, to the Unity area.
command is the command received from the web SDK delivered to the Unity SDK.

}Beware following.
Make sure to collect the events that occur in the in-app WebView through the Web SDK in a hybrid app setting. When collecting such events through the App SDK, event duplication will occur.
