Using Microsoft Edge (Chromium) Version 85.0.564.51 (Official build) (64-bit) and the web-push example https://tests.peter.sh/notification-generator works ok (after allowing notifications from that site):
However, when using WebView2 and the WebView2APISample from https://docs.microsoft.com/en-us/microsoft-edge/webview2/gettingstarted/win32 you get informed that permissions are required (first image above) but nowhere is there a button to grant such a permission.
Is there a solution to this?
