AR experiences in Adobe Aero are always initiated through a QR code and they do require iOS16, so some very old iPhones (like mine). It is supposed to work on Android devices as well, although I have not used one.
All programs used here were Adobe Creative Cloud apps and (as I understand it) available on lab computers. I am relative new to Adobe Aero and Adobe Animate, but I am not new to other Adobe apps like Photoshop and Illustrator, so I already knew how to use layers and draw vector shapes with the pen tool.
I would be very happy to sit next to you and work with you through this creation process, which is probably much easier than watching short tutorials on YouTube. You'll just have to allow time in your workflow to do this.
