How to publish an Add-On for Calendar as such?

Question

I'm developing a script which modifies events with certain criteria, I was able to publish it as Docs Add-On, and there are other options, but no Calendar. This guys nailed, but Calendar is not even as option in the G Suit Makerplace SDK (I managed Gmail).

Thanks for the feedback. At the moment the add-on framework only allows a developer to add a custom conference provider (this WebEx, etc), which isn't really applicable to a mass audience. If and when the framework become more general purpose I'll push the product team to make it generally available, since I'm sure there is a lot of great functionality this community can add to the Google Calendar experience.
