maybe this post skipped your view: List of module volunteers - #31 by revant_one
If not, you could contact module lead mentioned in above link for the domain of your interest and start getting involved.
For eg: I’m part of accounts module, and our Lead has decided to create Telegram group to discuss ideas and other things. We also had 1-2 meetings also. Once something substantial gets discussed or initiatives being taken, it is brought to the larger forum.
