I am trying to make a create lobby system where you can invite people to play with you, I have never done this so im still trying to figure out on how I do this. Here is the errors im getting and the block of line that Im using

Place the player on a table

TS:TeleportToPrivateServer(6940606115, code, {player})

Players: An array of Players to teleport

I am so dumb sometimes, Sorry about that
