How can I make players teleport to a map from lobby?

I am new to Roblox lua and I was wondering how I could make players from lobby teleport to a map. For example Two Players have joined the game A 30 second countdown starts All players get teleported to their team spawn The Game lasts for 300 seconds then players go back to lobby and the Map dissapears and another 30 second countdown starts and repeats the cycle.

It would mean the world to me if someone would help me :)

Thanks!

Loop through all the players in the game and teleport each one.

function teleportPlayers()
	for i, player in ipairs(game.Players:GetChildren()) do
   	--Make sure the character exists and its HumanoidRootPart exists
   if player.Character and player.Character:FindFirstChild("HumanoidRootPart") then
       
			 player.Character.HumanoidRootPart.CFrame = game.Workspace.TeleportPlace.CFrame + Vector3.new(0, i * 5, 0)
     --add an offset of 5 for each character
		end
	end
end

Put this code in a script and call the function using "teleportPlayers()"
