[Multiplayer] How do I hide a control panel at player's two screen and syncronize its functions?

Hello everyone.

I need some help here.

Any tips will be appreciated!

I need to make a game which the second player wouldn't see a control panel, visible only on player one's screen. This panel activates some videos and navigates between the different layouts of the game.

I also don't know how to synchronize all these events between both player's screens.

Could you help me, please?

Thanks.

use the multiplayer action "send message" and send anything you want
