I have an idea using functions updateHotspot() to update position and normal of slot button, but how to know their position when running animation.

We have an example for exactly this: https://modelviewer.dev/examples/annotations/index.html#animatedHotspots. If you use our editor to place hotspots, it automatically writes them in this form to work with animated models.
