How to request permission notification in WinForm WebView2?

[bhtri]

Hi everyone!
I want display the website to winforms application (in windows 10) through webview2, and have a look at the sample here.
But in my web, push notification permission is required, so is it possible to show a popup requesting permission like on the website? or is it possible to handle the event when permission is requested?

This is my code javascript on website

function requestPermission() {
    console.log('Requesting permission...');
    Notification.requestPermission().then((permission) => {
      if (permission === 'granted') {
        console.log('Notification permission granted.');
      } else {
        console.log('Unable to get permission to notify.');
      }
    });
  }

And error: An error occurred while retrieving token. FirebaseError: Messaging: The notification permission was not granted and blocked instead. (messaging/permission-blocked).

I searched and found CoreWebView2.PermissionRequested Event but when I implement it can't raised.

public Form1()
{
    InitializeComponent();
    Init();
    webView21.CoreWebView2.PermissionRequested += CoreWebView2_PermissionRequested;
}
private void CoreWebView2_PermissionRequested(object sender, Microsoft.Web.WebView2.Core.CoreWebView2PermissionRequestedEventArgs e)
{
    System.Console.WriteLine("Hello!!!");
}

Thank you very much
