WebBrowser Plugin - iOS Support

Hi,
I am currently using the experimental Web Browser plugin to open a web page and then bind an object to the browser using the BindUObject method. This allows me to communicate back and forth between the web page JavaScript and the UE4 C++ code. I have this functionality working for Windows and Android but it seems there is a lack of support included in this plugin for iOS.
The iOS BindUObject method is blank and there are a lack of files for implementing this functionality in the plugin source code.

Does anyone know how I would add this functionality for the iOS platform, example code or an alternative to achieving the two-way communication I need.

Thanks.
