问题 Whether by using createAddonMenu() or createMenu(), I can't create menu when add-on is installed through GSM, or when opened with "Integrate With Google" via G-Suite Marketplace SDK. "Test as add-on" via Script Editor works, installation via Chrome Web Store works, and I have no idea what might be wrong. I'm not sure if the script runs in the first place. I've tried existing solutions from StackOverflow such as calling functions in different order, but nothing seems to work. Does someone know
