We've previously talked about Messenger Rooms, which allows you to video call up to 50 people for free via Facebook messenger.
After being teased in a WhatsApp beta update, Messenger Rooms is now also available on Instagram, which comes as no surprise as both the aforementioned apps are owned by Facebook.
To access this feature, you'll have to update your Instagram app to the latest version.
After that, all you have to do is tap the 'Direct' aka DM button, and select who you'd like to create a Messenger Room with. You'll be able to select other users to join your call, after which you'll be redirected to the Messenger app. You'll also be provided a link for others to join the call directly.
Now, all that's left to do is to find 49 other friends to create a call with.
