I am a bit confused. I remember that in macOS13 I wasn't able to use continuity camera when hotspot was turned on. However I am able to use it on macOS15 without an issue.
Documentation still says hotspot cannot be enabled "Your iPhone is not sharing its mobile connection and your Mac is not sharing its internet connection."

PS: I am using M1 Pro + iPhone 16. When I was on Ventura I had iPhone 12
