Hello, im new with scripting in roblox and a have a small problem. I want this script to send the message to a specific team. But i don't now how to do it. Can somebody help me?

while true do  
    local maps = mapDirectory:getChildren() 
    local pickedMap = maps[math.random(1, #maps)]  
    local pickedMapClone = pickedMap:clone()  
    wait(1)
    pickedMapClone.Parent = game.Workspace      
    pickedMapClone:makeJoints()
    msg.Parent = game.Workspace
    wait(5)             
    msg.Text = "New call: " ..pickedMapClone.Name.."."      
    wait(10)    
    msg.Text = "Call ended"
