macOS Catalina will prompt users to allow Notifications from each app that makes a request. I don't see a Notifications payload for macOS Configuration Profiles like in iOS. I am requesting for this feature in future release of WS1.
I agree if it could be implemented into the product natively.
As a workaround, check out Profile Creator.
