Currently it’s in ‘early stages‘ and not live within games there hasn’t been much information about it being fully enabled in-game yet, it’s currently just studio but you should keep an eye on the announcement thread since this feature has just come out and it’s currently being worked on to upload your own custom videos and view within the game. (I don’t believe this is going to be in beta nor a beta feature).
The feature is currently still in BETA and will be released to the public soon, because the feature recently got released so they need to make it so it works for everyone’s screen
