Import models into my game

Hello,

Im watching this tutorial: https://www.youtube.com/watch?v=tNkvu-YUVro&t=241s

I have a reality composer project saved But she does not explain step by step what directory to import, how exactly to import it, and where exactly to import it to

I tried to drag and drop every folder level into xcode and also into finder, 1 by 1, nothing works. it does not recognize my contentBundle in code.

if someone from apple can upload 2 screenshots sowing the proper way to do this in 2026 it will be awesome

Thanks guys :)
