I am trying to ask user to grant permissions by Notification.requestPermission(), but it seems to work only in desktop browser.

In Android Chrome the prompt does not show up, but if I do alert(Notification.permission) then it alerts denied.

What else can I do?

You might have blocked the notifications in your mobile browser unknowingly Activate them again

Go to

Chrome => Settings => Advanced => Site Settings => Notifications and check Ask first 

Allow or block notifications from some sites:

1. On your Android phone or tablet, open the Chrome app Chrome.
2. To the right of the address bar, tap More More and then Info Information.
3. Tap Site Settings and then Notifications.
4. If you don’t see the setting here, this website can’t send you notifications.
5. Choose Allow or Ask first.

Ps: It was an issue with his service worker registration. Anyway this answer can be helpful to any other user.

Ok, I found out what it was - it seems I have problem with serviceWorker registration, not with permissions.

Anyways, thank you Sravan
