I use a note taking app (BlankBook) to draw diagrams on my iPad while talking to people on Zoom. It works very well, but sometimes I want to point to something on the screen.
What I would like is for something visible - like a circle - to appear whenever I touch the screen with my finger. Is there an app or some kind of setting that will do this? I think I've seen something like this in screen-captured videos before, so I think it's possible.
I have seen a few pages like this one that say you can do this by enabling "AssitiveTouch" and creating a custom gesture, but that really doesn't work very well. (When it's turned on the app can't receive any gestures other than a single tap, so you have to turn it off in order to draw on the screen, then turn it on to point at what you just drew, turn it off to scroll, turn it on again, etc.) So I'm looking for a different solution, other than AssistiveTouch.
In case it makes a difference, I should mention that I'm using Zoom on my Macbook rather than the iPad, and sharing the iPad screen via the USB cable.
(Note: there is a similar question from 2018, but that question is specifically about recording a user's interactions with the device for development purposes. The link in the only answer is broken, but is it's this app it's really quite specific to web development - it wouldn't work for my issue.)
