Facebook recently debuted Messenger Rooms for users around the world. This feature allows users to create group video chats that can support up to 50 people. Once you’ve created a Messenger Room, you can edit the Room later on to make changes. For instance, if you forgot to invite someone to your Room, you can add them to the list of people who are allowed to join. Our guide will show you how to edit a Messenger Room from within the Facebook mobile application.
