Configuration in Webview

Question

Good afternoon, I have an application ( in Xamarin for android) where within it opens a webview on a link of a platform courses I have... but there is a big difference between I open this platform on my webView and in a browser like Chrome for example... In webView the video of the VIMEO platform, when I press play, I can’t pause and leave it on fullscreen

Already in google Chrome ( by the same device ) , it is possible to pause, put in fullscreen mode etc...

What do I need to do configuration on my webview so it doesn’t have these problems? Thank you

Here is an excerpt from the Activity code of the webview:

protected override void OnCreate(Bundle savedInstanceState)
        {
            base.OnCreate(savedInstanceState);
            //MainActivity Url_Nav = new MainActivity();
            // Create your application here
            SetContentView(Resource.Layout.Nav);
            mWebView = FindViewById(Resource.Id.webNav);
            mWebView.Settings.JavaScriptEnabled = true;
            mWebView.LoadUrl(MainActivity.url);
            mWebView.SetWebViewClient(new WebViewClient());

        }

    }

    public class WebClient1 : WebViewClient
    {
        public override bool ShouldOverrideUrlLoading(WebView view, string url)
        {
            view.LoadUrl(url);
            return true;
        }
    }

Thank you !
