PushManager.permissionState()
Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
The permissionState() method of the PushManager interface returns a Promise that resolves to a DOMString indicating the permission state of the push manager. Possible values are 'prompt', 'denied', or 'granted'.
Note: As of Firefox 44, the permissions for Notifications and Push have been merged. If permission is granted for notifications, push will also be enabled.
