How do i use RPC's to set a object active in the hierarchy for all Players in the room and also how do i synchronize UI events focused on a VideoPlayer (Play, Pause etc.))

I have a Plane Game object with a VideoPlayer component attached and i want it to be set active for all players in the Room via UI Button Click.

There is also a UI Canvas child of the plane which Controls the video such ass play, pause, skip and close. Is it possible for all player to control the video via the UI? If so how do i implement this?
