Hot Corners with Dwell Control/Assitive Touch Not Working

In using Assistive Touch, I’ve discovered Dwell Control and what interest me are Hot Corners.

I’ve enabled Dwell Control, but the hot corners do not work.

Whether I disable or enable a Fallback action or not, nor by using the Dwell Tap Cursor from the Assistive Touch Menu.

Does anyone else have issues with trying to get Hot Corners to work?
