I want to make an invitation ui, that is, when a player (1) uses an item, a ui will appear that will have the function of selecting one of the active players and sending him an example invitation message (do you want to join my team) and player (2) will receive a user interface with the message that he wants to be part of (player 1's) team if he answers (yes) a Tag will be added that is like the one that player (1) has and if you answer no to Player (1) you will receive a notification that Player (2) did not accept your invitation.
someone could help me?
