Setting up a group or user with a number that multiple users can access.

We are trying to set up a group number that can receive texts and calls that multiple people can access from their zoom.  I'm struggling to figure out a solution.  I can set up a new user but then that involves signing into the other account and that isn't going to work.  It would be best if it was possible to have a chat or phone show up with its own phone number that multiple people can access.  Any ideas?
