The Notification add-on is a Tutor LMS Pro feature that allows you to send out two types of notifications to the users of your Tutor LMS Site: On-Site Notification and Browser Toast Push Notification.

To see these settings, you first have to enable the Notification add-on from WP Admin > Tutor LMS Pro > Add-ons. For more information on this feature, please visit its dedicated documentation.
