Camera not detected in Ubuntu 24.04 on XPS13-9320

This thread seems to be closed, saying there is no solution for the "no camera found" problem as of July 2024.   However, this page, Ubuntu oem-somerville-tentacool-meta package, seems to say there is a possible solution published in December, 2024.  As I haven't seen anything anywhere that confirms this to be the solution, I would like to know:

1. if indeed this is a good solution and
2. what the best would be to go about implementing it.

(I'm relative new to Linux.)

Thank you.
