So recently someone in a server I'm in said that the first person to type a certain command into chat would get a reward. The thing is they wanted it to be shown in the public chat. Someone somehow did it and it showed up perfectly fine in chat. I was wondering how they typed a command that should do something but didn't do something or give any error message. The command was "/Lobby" and someone typed it without being sent back to the lobby or without any error and it showed up in the public chat. I have searched for how to do it but have found nothing.
