Overriding / modifying the default PencilKit edit menu?

Is it possible to override or add buttons to this menu, which appears when I tap on a PKCanvasView?

I updated to iPadOS 16.1 20B79 yesterday. This menu no longer shows up upon single tap / long press. I couldn't find this change mentioned in the release note though. Has anyone observed the same?

More observations: right clicks on a physical input device (mouse / trackpad) still bring up a context menu with these two buttons. The Select All is still unacceptably slow if you have a larger canvas / large amount of strokes (this was the reason why I wanted to get rid of this menu). I wonder how the upcoming Freeform app is gonna tackle this; and if it does, whether the API will be updated accordingly.

I am seeing the same behaviour regarding the edit menu not showing: https://developer.apple.com/forums/thread/718677
