There are a few pages with solutions to this although when I enter the game, open Chat → ChatModules → TeamChat, I delete these lines of code shown below. I rejoin and it still contains these lines of code. How do I make this change permanent?
local msg = ChatLocalization:FormatMessageToSend("GameChat_TeamChat_NowInTeam",
string.format("You are now on the '%s' team.", player.Team.Name),
"RBX_NAME",
player.Team.Name
)
speakerObj:SendSystemMessage(msg, channel.Name)
