How to reRequest permission for showing notifications in Firebase Cloud Messaging?

Question

I'm developing the push notifications for web app with Firebase Cloud Messaging.

After the first run I got request notification promt because of this code:

const messaging = firebase.messaging();
    messaging
        .requestPermission()
        ..........

I have granted the permission, but now when I visit this page I didn't ever see the request for permission promt because I already granted the permission while the first run. How can I unsubscribe my device to see permission requests again?

See:

• https://support.google.com/chrome/answer/3220216?co=GENIE.Platform%3DDesktop&oco=0&hl=en
• chrome://settings/content/notifications
• https://firebase.google.com/support/release-notes/js#cloud-messaging
• https://developer.mozilla.org/ja/docs/Web/API/notification/requestPermission

Deprecated requestPermission(). Use the native browser API Notification.requestPermission() instead.

If firebase version is newer 6.0.4 then you should use Notification.requestPermission() .
