WKWebView

Please give me a chance to ask you.
I would like to use WKWebView. I wrote following source code.

void Start()
{
	webViewObject = (new GameObject("WebViewObject")).AddComponent();
	webViewObject.Init((msg)=>{
	if (msg == "clicked") {
	webViewObject.SetVisibility(false);
	}
	},enableWKWebView: true);

	webViewObject.LoadURL(url);
	webViewObject.SetMargins(50,100,50,50);
	webViewObject.SetVisibility(true);
}

But I could not compile correctly with this source code.
How can I enable WKWebView?
Is there anything my mistake in my source code?

Best Regards.

Start by checking the provided Unity Start() snippet, especially the Init call with enableWKWebView and the WebViewObject setup. Compare that call with the project's documented API or entry point for WKWebView and identify the compile error; done means the example compiles and enables the requested web view.
