Notifications API or how to track a user's click on "x"?

Question

JavaScript

Actually the question is quite simple, but I can not find the answer to it for quite a long time.
The site has a push notification. It is necessary to put an event listener on a click or action on this push and "understand" that "x" was pressed, that is, the push was closed.
granted, denied, default statuses I get, but they in no way tell me the status of the modal - whether it was closed or not...
For example:
1) The user is logged into the site.
Notification.permission will be default
2) I saw push clicked on the cross push closed
Notification.permission will be default
Actually the question is how to get the state of this push?
And how to determine that the user closed the push with a cross?

Answer 1

Here is the solution:

Notification.requestPermission(function(status) {
        if(status === 'default') {
            console.log('Push closed!');
        }
    });

Answer 2

maybe this will help or suggest ideas

self.addEventListener('notificationclose', function(event) {
  // Do something as the result of the notification close
});

seems to be what you need, but I don’t know much about push notifications
