If you no longer need a notification setting, you can delete it from Control Center. If you only want to temporarily stop notifications (e.g., if you are on vacation), you can edit the notification setting to disable it and then activate it again later.
In the upper-right corner, click your username, then click Notifications.
Control Center lists all your notifications. If you're a Control Center system administrator, you see your notifications by default, but you can use the list to select another user in your organization to view their notifications.
Click Notification Management.
Control Center lists all notification settings for your Control Center profile.
On the row for the notification setting you want to delete, click the icon.
In the confirmation window that appears, click OK.
