macOS Catalina will prompt users to allow Notifications from each app that makes a request. Administrators can manage these prompts using a Configuration Profile. If running Jamf Pro 10.19 or later, I suggest instead using this manifest: https://github.com/talkingmoose/jamf-manifests/blob/master/macOS%20Notifications%20(com.apple.notificationset…

Purpose:       Create configuration profiles to manage app notifications
               Upload the configuration profile to Jamf Pro or save to your desktop
			   
Configuration: To upload to your Jamf Pro server, edit these lines before running the script.
               The API-Editor account needs the Create privilege for macOS Configuration Profiles in Jamf Pro

               organizationName=\"Talking Moose Industries\"

Usage:         \"$0\" [/path/to/application]

               Questions are followed by allowed responses with [default] responses in brackets.
               Responses are case insensitive and accept the first letter or entire word.
               Press return to accept the default response.
			   
Example:       $ \"$0\"

               Path to managed app (drag app into this Terminal window): /Applications/FaceTime.app
               
               ...

               or

               $ \"$0\" /Applications/FaceTime.app
               
               Allow Notifications from FaceTime ( [Yes] No ): Yes

               FaceTime alert style ( None [Banners] Alerts ): A
               Show notifications on lock screen ( [Yes] No ): n
               Show in Notification Center ( [Yes] No ): true
               Badge app icon ( [Yes] No ):  
               Play sound for notifications ( [Yes] No ): NO
               Critical Alerts Enabled ( Yes [No] ): FALSE
               
               Add another app ( [Yes] No ): n

               Upload to Jamf Pro or Save to Desktop? ( Both [Upload] Save ): U

               Your new Notifications configuration profile for FaceTime was uploaded to Jamf Pro and is ready for scoping.

               Would you like to view the profile now? ( [Yes] No ): yes"

Old reply but desperately looking for a solution to this issue and I am not having any success using this on Big Sur. The profile isn't getting picked up by Jamf and even when installed manually it has inconsistent success with different apps.

@curdZ Jamf has since added Notifications as a payload to Configuration Profiles. You should use that instead.

Wow I'm blind, I'll definitely use that. Thanks for your reply!
