Device detection system

[AmirSafavi]

Well, here I have a system to detect the player's device connected to the server, but there is a problem
For example, if a player with the name Amir_Safavi connects to the server and is a PC player, his name will be changed to Amir_Safavi[PC]
Well, now the same person can connect to the server with another device named Amir_Safavi, actually two devices with one account
So now I need an If in OnPlayerConnect to prevent a player with this name from re-entering the server and kick him.

But I don't know what if to write for it
Can anyone advise?
If yes, please write it to me so that I can copy and paste it in the game mode
