and click the Edit button to go to "Messages" and the "Request read confirmation" text box:

Request read confirmation
Regardless of which page of the app the user has opened, when a new message is published, it is displayed as a pop-up. By default, the pop-up disappears after 10 seconds and the message is displayed only in the message list and, if applicable, on the home page.
If you require a read confirmation, the pop-up will not disappear automatically, but must be actively closed by the user within a specified time. After the specified time, the pop-up will disappear, even if the user has not closed it.
Note: The read confirmation only applies to the display of pop-ups. It does not affect the display in the news list or on the home page.
To send the message at the set publication time, click on the button:
