How do I detect if someone has removed my Google Workspace Add-On?

I'm creating a public Google Workspace Add On and I'd like to detect when the add-on has been removed.

I don't see a way to do this in the documentation.

Is this possible?

Solution

After extensive research through official documentation I can confirm that at the date of this answer, there's no option to know when a user has removed your Add-on, either via the Add-On itself or the Google Workspace Marketplace.
