how do i make a game teleport without that game being in recent games?

i was making a game then i realized it would be to laggy so i separated it into 3 parts in different games. the teleporter works fine but the games show up in resents and i don't want the players to play anyone i want them to start from the start. should i make the other games private for something? or its just the scripts?

here is the script i use, its located in Workspace>Part>SCRIPT

local TeleportService = game:GetService("TeleportService")
local gameID = "game id"   

function onTouched(hit)
    local player = game.Players:GetPlayerFromCharacter(hit.Parent)
    if player then
        TeleportService:Teleport(gameID, player)
    end
end

script.Parent.Touched:connect(onTouched)
