This isn't a perfect solution, however, you could leverage a Storyline block. Insert the YT video via Storyline. Create an offscreen timer that would unlock the continue block after X time.
In the example below, I put the youtube video on a storyline slide. Then I added a timer that counts down seconds. When it reaches X seconds, I mark the course complete which unlocks the continue button. In this example, it unlocks after 10 seconds.
