I'm supposed to add the package from this link to my project https://gitlab.com/eventlabprojects/quickvr.packages/com.quickvr.quickbase.git but it's not working. It worked for everyone in my class but me, and I'm not sure if it's because of the Mac I have or what exactly.
I'm using the installer Unity LTS for silicon:
My Mac is the 14-inch 2021 MacBook Pro with the Apple M1 Pro chip and it's updated to Mac OS Ventura 13.0.1.
This is the error that keeps popping up, something about xcrun?

P.S. I'm not a developer, I'm a student who is trying Unity for the first time and STRUGGLING.
