Auto-join teams for fresh registered users?

I am using latest with docker. I’ve been able to install it within 10min, great job guys!

I was wondering if it is possible for new registered users; to add them into a specific team automatically.
I know it is possible for auto-join channels, but I ask here for auto-join a team by default.

Many thanks

I did answer this in open

The answer is I don’t believe you can in CE - think it is a EE feature. Might be some APIs you can run.

I can’t find any API Documentation, is there a list of something? Thanks for your help.
