Permission UI UX
Websites must display a permission prompt to subscribe the users to web push notifications: let’s see how and when you can display the notification prompt and the different ways to present the prompt to the users.
Display the prompt for web push notifications multiple times
Usually the prompt for web push notifications is displayed only once, the first time that the user visits a website. What if the user blocks the notifications? Is there a way to show the notifications prompt when the user visits the website again?
Force the user to subscribe to web push notifications
Forcing the user to subscribe to push notifications is probably not a good choice for most websites. However there are some specific situations where it makes sense to do that.
