ServiceWorkerRegistration.getNotifications()
The getNotifications() method of
the ServiceWorkerRegistration interface returns a list of the
notifications in the order that they were created from the current origin via the
current service worker registration. Origins can have many active but
differently-scoped service worker registrations. Notifications created by one service
worker on the same origin will not be available to other active services workers on
that same origin.
Syntax

.then(function(notificationsList) { /* ... */ });

var options = { tag : 'user_alerts' };
