This depends greatly on what type of game you have and what connection players will have. Also, this depends on which software you use to publish your game.
Are you going to have:
A Peer to Peer connection where all players are equal?
A Host to Client connection where 1 host delivers data to the clients?
A Server to Client connect where all players are clients accessing one server?
Or something else.
Either way, you can look into PUN2 by Photon, Google Firebase, MonoDB etc

Thanks for your response. Not being the game designer, I'll have to get the answers to those questions. At this time, I have my teams in Zoom, divide them into breakout groups of 6, and then they receive the user name and PW for the day and go off into their separtate teams to play.
Thanks for the referrals of what to look into.
