How to make GUI visible to everyone, but only one person can use it?

Hello, I am working on an RPG game in Roblox, to be exact its an online RPG where friends fight as a team, and if one of them encounters an enemy, they all get brought to a turn based combat arena, and they are all fighting the enemy in turns (like persona if you’ve heard of that, but instead of a cpu or you controlling your team, its another player (your friend to be precise)), now the thing is, I want everyone to see the attack selection UI (Like if the player who’s turn it is goes in the special attack menu all other players see that menu too, or if he enters the melee menu, they see that too etc.), but only the player who’s turn it is, will be able to enter the menus and use the attacks (meaning they can’t use buttons or anything, they just get the same UI as the player who’s turn it is, and every action he does gets mirrored to their UI, but they don’t actually have any control over it.).
