User Profile

I have developed Applescripts on Mojave and exported them as apps for Mac users in my department. These ran as expected. I can run them fine on Catalina on my Mac, but cannot make them available to other Catalina users, despite code signing them. Do I need to go through the notarisation process, use XCode, or some other method to make them available as apps to other Mac users in my department? (They do not need to be made available through the app store.)
