I tried that with an iPad once - if there's a way to do so without looking faintly ridiculous I'm all ears. But I'm an Android person as far as phones go, lack of a standard system wise undo command isn't quite enough to send me back to Apple.

My solution to this would be to enable the Assistive Touch button and set its double tap action to 'shake'. If you don't want the button all the time, create a personal automation shortcut which runs when a specific app opens and closes, setting Assistive Touch on and off as you wish.

Alternatively have Voice Control enabled and say "undo that".

There is also a three finger gesture: https://appleinsider.com/articles/19/06/27/new-ipados-button...
