Banners embedded in USDZ files?

Just getting familiar with XCode. Using Reality Composer a lot now. Ready to try coding along with with Reality Composer.

Saw this demo (see link below), but I don't want to use a web server to retrieve banner information, I would prefer to embed this information directly into the USDZ file to be read with AR Quick Look.

**Two questions: **

  1. How can you get a banner like this when you open an USDZ file and edit the banner information directly (within the file itself) without using a URL?

  2. In place of the call to action button (for Apple Pay) in the demo below, I'd like to use that button to either call a phone number, send a text, or go to a web URL.

Link to Apple's example with Apple Pay (see custom examples section, like for the kids' slide example on that page). https://developer.apple.com/augmented-reality/quick-look/

Scraps are welcome, hungry to learn.
