No Camera Found on laptop (Microsoft Surface Book 2) #1468

I am new to Linux (and NOT a programmer) & I cannot seem to get either of the built-in cameras to be recognized. What am I missing to be able to share video &/or my screen in a Google Meet, Zoom or Teams meeting?

Here are the details about my laptop:

Hardware Information:

• Hardware Model: Microsoft Corporation Surface Book 2
• Memory: 16.0 GiB
• Processor: Intel® Core™ i7-8650U × 8
• Graphics: Intel® UHD Graphics 620 (KBL GT2)
• Graphics 1: NVIDIA GeForce GTX 1060
• Disk Capacity: (null)

Software Information:

• Firmware Version: 394.779.768
• OS Name: Ubuntu 24.04 LTS
• OS Build: (null)
• OS Type: 64-bit
• GNOME Version: 46
• Windowing System: X11
• Kernel Version: Linux 6.12.3-surface-2

I'm not sure I remember everything I've tried so far, but I found this: https://github.com/linux-surface/linux-surface/wiki/Camera-Support & the commands returned "command not found" for me, so I suspect I don't have all the required elements/dependencies even though this is a fresh install & "all packages are up to date". I think I found the bin files, but they are in a zst that I don't have permission to uncompress.

I added the app Cheese that opens with the warning "There was an error playing video from the webcam", and the camera app still says "No camera found".

I also found this page: https://libcamera.org/getting-started.html & copy pasted the first section of code to install libcamera-tools that I was told should contain the camera, but I don't know how to to access or what to do with these tools. I also don't know how to check to see if I have all the required dependencies.

I booted in BIOS a few times & turned everything on, but now I believe I have the IR camera off. So I can change these settings again if need be.

There were other things I tried from old camera related questions, but nothing has worked for me so far.
