Rigging tutorial for Animate

I’m finally going through the Animate Pro TB tutorials 1 by 1.
I was doing fine with most of them, which I found very helpful
(I’ve been using TB Animate for years, so it was mostly review).
But, my progress came to a crashing halt when I reached the
“rigging in the network view” lesson. I was baffled.
But, she mentioned there is a video tutorial for correctly rigging
a hierarchy in Animate. I’d LOVE to see it, but couldn’t find it.
Can anyone point me to it?

It looks like tutorial 9.10 is Rigging (Animate)
