Running Your Chess Club Online

how can i invite friends to my new created team? Can't find a function ord button for that.

What we would like to do is run an entire league. I normally play in 4 OTB leagues. I have started a team here and some of our other clubs have done likewise. It would be better if we could replicate a league rather than playing tournaments. Is there a way to do this or does Lichess have any plans to implement this ability?
