The command just came out but when someone invites me and i click Join, it redirects to a normal room:

• Magicalorb invites you to join the 15 to Life's tribe house. [join]
You just entered room [5]. Type /room RoomName to create or join an existing room.

same happens to me and every time it just changes to random room

People who were invited to a room can use the /module modulename command.
