Morphing different shapes by using the adjustment handle in PPT 2019

Normally the Morph transition does not work while using non identical objects. In a previous article I explained that this can be circumvented by renaming the objects in the selection pane on both slides. See my article:
Morphing with non identical shapes

There is another solution to the problem, be it a limited one. You can use the adjustment handles to morph an object into another one. In fact it is the same shape that gets transformed not two different shapes, a little bit of cheating.
For instance, let's say you draw a rounded square (drawing tool rectangle with rounded corners, holding down the shift key while you draw) on one slide. Then you copy the first slide and you adjust the object into a perfect circle. Look at the video below which shows you how it is done.

Unfortunately not all shapes are equipped with adjustment handles. In the example below you can see shapes that do not have one (left) and shapes that do have one (right).

Depending on the shape you draw the effect can be spectacular or not.
Watch the following video with some interesting examples.
