Huskylens2 vision tracker code

I have been trying to get this project to work 

https://github.com/MukeshSankhla/HUSKYLENS-2-Vision-Tracker

Everything is printed and assembled but the code provided does not work with firmware 1.2.2. My attempts to downgrade to firmware 1.1.5 weren't successful (but this doesn't seem to be a good solution anyway).

Does anyone have any face tracking or object tracking code which works for this project or a similar one? I have tried many times to write code using Claude but with very limited success. I don't know if the data coming from the camera is reliable.

I can post some of the code from the attempts I have made if that helps.

Ultimately, I would like it to track objects but I have also tried facial recognition as Claude seemed to think it was more reliable.

Thanks,

John
