Facebook described it "Watch Videos Together " according to the screenshots posted in twitter by Ananay Arora?. This feature would let its users chat about the video at the same time, though it might be the same as videos from the Facebook platform, but for this feature, it only allowed people who are invited in a group chat.

A Facebook representative told CNET that the company is "always testing new features in Messenger," and doesn't have anything else to accord for now.
Watch Party exists on Facebook but could be more attractive as a chat feature in the messenger app.
