Browser also asks camera permission in ios webview

I am having a Xamarin.Forms Prism application. It is using a WKWebView in ios Project to display a web page. In that page, other than the permission from the iOS, a permission popup from browser is also being displayed. Can anybody please help me with this? This is happening only in iOS.

This thread helped me to solve this problem. Implement a class which is inherited from WKUIDelegate.

  public class CustomWebViewDelegate : WKUIDelegate
    {
        [Export("webView:decideMediaCapturePermissionsForOrigin:initiatedByFrame:type:decisionHandler:")]
        public override void RequestMediaCapturePermission(WKWebView webView, WKSecurityOrigin origin, WKFrameInfo frame, WKMediaCaptureType type, Action<WKPermissionDecision> decisionHandler)
        {
            try
            {
                decisionHandler(WKPermissionDecision.Grant);
               base.RequestMediaCapturePermission(webView, origin, frame, type, decisionHandler);
            }
            catch (Exception e)
            { }
        }
    }

Add this statement in the Renderer class.

webView.UIDelegate = new CustomWebViewDelegate();
