Run a scan to share what does and doesn't work on your machine so that others can see. Don't worry about it. This is a good thing for everyone and not some exploit. Check if others have scanned with the same hardware. Look at what kernel they are running and if it has the same problem or notes. You may see the hardware label and find other machines with the same that may or may not be working.
The important part is the hardware id of the camera, you have to search for this, drivers and kernel modules use this number to check if they are needed:

I found a documented laptop with this camera: https://wiki.archlinux.org/title/Dell_XPS_16_(9640)#Webcam
They link to some patches there, it may work with that
As I see the date of the patch is this year March, I guess simply the laptop is too new. If you don't want to fiddle, just switch to some rolling release distro, and the patches will be merged upstream soon. After a kernel update your camera will magically start working. This would be the easiest solution if you can live some more months without the camera.
