ROBLOX Just took down a bunch of my groups places becouse our Coms GUI does not comply with the new filtering, how would i add it to this script?

Edit I can now see my messages being posted, but no one elses

local channels = script.Parent.Channels
local data = workspace.OfficerRadioSystem
local channel = script.Parent.Frequency
local on = script.Parent.On

local player = game.Players.LocalPlayer
local MACO = 1045203
local Temporal = 983872
local Starfleet = 947351

function transmit(msg, sender)
    local  filteredmessage = game.Chat:FilterStringForBroadcast(msg, sender)
