There is an error in the Chat Message script? Gives error saying it lacks permission?

This script is located in a normal script in workspace.

game.Players.PlayerAdded:connect(function(nP)
	nP.Chatted:connect(function(msg)
		local gcolor = nP.TeamColor
		if gcolor == game.Teams.Host.TeamColor then
			if msg == "!bubble" then
				game.Players:SetChatStyle(Enum.ChatStyle.Bubble)
			elseif msg == "!classic" then
				game.Players:SetChatStyle(Enum.ChatStyle.Classic) 
			elseif msg == "!classicbubble" or "!bothchats" then
				game.Players:SetChatStyle(Enum.ChatStyle.ClassicAndBubble)
			end
		end
	end)
end)

Gives this error: The current identity (2) cannot SetChatStyle (lacking permission 1). Is there a way to fix or get around this error?
