If you use the macOS Creator on a regular basis, you can create an application that will appear directly in your Applications folder

This will save the script to a hidden folder in your Home folder, and the application simply runs an automator command to launch that script.

Unzip the "app_files.zip" file.

Open the "Build App.command" script.

You may have to right-click the script and choose "Open" if macOS refuses to open the script.
