How to embed clickable dots into USDZ file using code

My app auto-generates USDZ files, and I want to make them interactive by adding some interactive dots into the file and let user click them. One possible way is to embed clickable dots into the USDZ file and convert it to .reality file. But how can I do this with code?

Below is an example that I want to achieve.

Hi Xia_Su:
