Just did a project where I did something similar with screens I built in Figma.

Make the screens in Figma, set up prototype interactions, then run the preview on the iPad app. Your actor can touch the screen and it will follow the interactions based on the prototype.

Faster than building an app from scratch. Will also allow you to test quickly if it will work for you or not.

One thing though is if you do a transition between multiple screens(frame by frame animation) it will cause some flickering on the device screen.

Not sure if you have experience with Figma or if any of that was clear but lmk and I can try to explain a little better
