What’s Push Notification

Web applications use Push Notification as their primary method of communication with their users. We receive a notification consent alert when we visit any website, with the option to approve or reject notifications. Websites develop these alerts to obtain permission to display notifications with the most recent updates, news, and other information. If we give the notice to display permissions, the notifications will be pushed to website users by the website administrator.
