Export as USDZ ?

Hi, I saw that you can choose the AR option while exporting your files and you would get a preview of how this would look.

I have tried to transform my PNG files to USDZ, but failed to get it to work. Normally USDZ files would be used for a 3d object, but would it be possible to implement a function to directly export your drawings as a working USDZ file? Since you already manage to show the preview, I was wondering if it was very hard to implement?
