Push Notifications for an end user
Push Notifications are instant clickable messages/cards which appear on your desktop or mobile device. These notifications can be pushed to you by the websites that you choose to receive notifications from. You can think of these notifications as app notifications, unlike the fact that you do not need to have any app installed and just need to click on a button once to subscribe to a website and start receiving notifications. Push notifications can be delivered to your desktop & mobile devices, even when you don't have a browser open.
