Releasing items from one queue to another only if the second queue is empty

I want the queue 2 to release items to queue 3 only if the queue 3 is empty. How is it possible to do that?

When an item enters Queue3, use the On Entry and On Message triggers to close the input after some small amount of time (to allow for items to enter in that instant).

In the On Exit trigger, open the input again once the last item exits.
