How to Teleport everyone in my game to another game using TeleportService?

local Teleport = game:GetService('TeleportService') -- Get Teleport Service
function teleport(Teleport)
    Teleport.CustomizedTeleportUI = true
    for l,y in pairs(Teleport:GetChildren()) do
        o(y)
        if Teleport:IsA("Player")
            then
            game:GetService('TeleportService'):Teleport(IdHere) -- Place Id specified 
        end
    end
end
teleport()

I want to teleport everyone who is a Player to another game without prompt hence why I used CustomizedTeleportUI because it does not prompt if I use it. But when I tested the script it does not work, some feedback would be very nice
