I resolved this and am now able to access the "Settings" and properties that I was trying to find. I found there were various versions of the "WebView" component. Apparently there is a "Shared" WebView that is generic, and then there are platform specific "WebViews" that are part of separate sub-projects for each device type (android, iOS, etc). I had to create my own I was able to use a project called "JSWebView" as example for each "WebView" type to create a "CustomWebView" and "CustomWebViewRender", here is the link to the sample project: https://github.com/GuyMicciche/JSWebView
