My guess is that this is something the user has to explicitly check in the Privacy & Security "App store and identified developers" and in addition, when someone tries to execute the binary, the user has to explicitly allow (again) in the same privacy & security to execute that binary. That's how it works AFAIK.

If you distribute apps not signed/notarized, users have to explicitly allow them - there is no way that you can just double click on the "MyProgramm.app" icon and it works.

Another trick is to enter the "MyProgram.app" folder and double click the binary inside. That might work, although it's a pain for some.
