How to add apps on the watch to the dock using Favourites view

I have been managing favorites in the dock for the last couple of years, but noticed after the introduction of Watch OS 6 that the old method no longer worked. I, too, am still looking for a solution and would appreciate ideas and work-arounds. The Watch OS will still allow the dock to keep track of those apps recently launched, but I really want my favorites back. It is still possible to remove old Favorites from the dock, but I have not figured out a way to put apps back into the Apple Watch dock. I am using an Apple Watch 4 with cellular, running the latest Apple Watch operating system. My iPhone is a 10 R, also running the latest version of iOS 13. I use VoiceOver on both my iPhone and my Apple Watch.

Thanks for the feedback. Unfortunately, I cannot find the Insert button, which did function in the past. However, I tried just dragging the Activity app into the dock and it appeared to work. That was not the app I wanted to move, but at least it appears, at first glance, that I had some kind of success. My big problem, I suspect, is that the Insert button is not showing up in VoiceOver for me.
