How would I temporarily mute TTT's radio button (quick chat)?

Garry's Mod coding
#1

We recently picked up this addon that freezes players and stops them from talking in both chat and voice chat.
However I can’t figure out why it won’t mute stuff like ‘ttt_radio traitor’
Here is what I’ve got so far:



function CRYO_CantTalk()
	if (CRYOGRENADE_SETTINGS.PrintInChat) then
		chat.AddText(CRYOGRENADE_SETTINGS.ChatMessageColor, CRYOGRENADE_SETTINGS.CantChatMessageContents)
	end
end

hook.Add("PlayerBindPress", "CRYO_PlayerBindPress", function(ply, bind, press)
	if (!CRYOGRENADE_SETTINGS.AllowPlayerVoiceChat and press and string.find(bind, "+voicerecord") and LocalPlayer().m_bIsFrozen) then
		CRYO_CantTalk()
		return true
	end
end)

You can return true on the hook TTTPlayerRadioCommand to block any messages from being sent
