Within each workstream category there are private and public rooms.

R-role is for public (accessible in role selector); this allows verified foxes to see any public rooms.

B-role is for bounty/helper/contributor; this role sees some private workstream rooms.

W-role is for official workstream contributors; this role sees all of the back end of those workstreams including voice channels.

If unclear which role to add, confirm with the workstream leader/requestor.
