Quiet notifications were enabled by default but starting Microsoft Edge version 88 they will be disabled by default instead to make Adaptive Notification Requests work.

Microsoft is now taking a smarter approach with how Edge handles website notifications.

Edge Bar is a sidebar that can serve as your mini browser to perform functions like searching, browsing, checking, emails, weather, news, etc.

In Microsoft Edge 84, Microsoft introduced "quiet notification requests" by default to tame spammy alerts from websites that want permission to issue notifications to users.
