Bedrock pause screen actually pauses

This isn't my idea I saw it from someone else but I wanted to share how I would make it work. So in java you can pause, but you can't on bedrock. I would add it to single player, and for split screen I would either make it to where if player 1 pauses it takes player 2, 3, and 4 to the pause screen as well and all other players will have to wait till p1 unpauses. The second way I would add it is if all players are pauses at the same time it pauses the game
