How to register player using UI buttons?

Wait, is it possible to use (Message.Player) or (Player) with the Cinematic Sequence in Verse? I couldn’t get it to work, and Ray seemed to say it wasn’t a thing. I would really like to be able to play a Cinematic Sequence for only one player not everyone, and I thought it wasn’t possible with Verse. Calling Play() for Cinematic Sequence Device? - I can't get it to for "Instigator Only", only plays for "Everyone."
