How to connect to gitea?

[BackSeat]

According to this page, to enable integration with github I should go to Settings, Integrations. That seemed like a good place to look for integrating with gitea; however, my super-productivity doesn't have an Integrations menu under Settings. I've checked on both the Linux and Mac versions (16.5.4).

I also found a link on this page to "See integration docs", but other than telling me that super-productivity will integrate with gitea and others, it offers no clues in how to achieve that integration.

Where should I be looking to configure gitea integration?
