Wireless connection issue - no longer syncing

So I had a person attempt to repair the stick drift issue it was having. On return, the repair person said that the wireless wouldnt work for them with their xbox ( this was working before I gave it to them) and they said it was never set up for xbox...
Im looking at the instinct and the ps version and I think they went through and did the repairs of the ps5 on the instinct... but I am unsure about its wireless sensors. the button does engage and light up, but no devices, windows, ps, or xbox can see it anymore.

Any suggestions on what I should focus on? or what to check to see might need to be replaced?
