How do I stop this while wait after the task is done?

[NoobArmyHype]

Hello! I have a script that checks when a player stops doing something. I have it all working but I want this while wait script to stop after the timer is done

Script:

game.ReplicatedStorage.RemoteEvents.PlayersDone.OnServerEvent:Connect(function()
	ScreenGui.Start.Start.FinishedButton.Visible = false
	ScreenGui.Start.Start.Time.Visible = false
end)

game.ReplicatedStorage.RemoteEvents.GameStart.OnServerEvent:Connect(function()
	while wait(1) do
		ScreenGui.GameScript.Time.Value = ScreenGui.GameScript.Time.Value - 1
		ScreenGui.Start.Start.Time.Text = ScreenGui.GameScript.Time.Value
		if ScreenGui.GameScript.Time == 0 then
			print("Time finished.")
		end
	end
end)

localscript:

while wait(0.1) do
	if script.PlayersFinished.Value == PlayerCount then
		print("all players have finished their sentences.")
		game.ReplicatedStorage.RemoteEvents.PlayersDone:FireServer()
	else
		print("All Players have not finished their sentences.")
	end
	if ScreenGui.GameScript.Time == 0 then
		print("Time finished.")
		game.ReplicatedStorage.RemoteEvents.PlayersDone:FireServer()
	end
end

Use break to exit out of the loop.
