Most of these airbags come from the same place, this looks similar to the one on a 2016 Nissan I was driving around for about 9 months before we got our Jeep. Try expanding your youtube search out to other brands and skim through checking to see if the overall design is the same as yours (two holes, likely). I had pulled my Nissan airbag out once while installing remote start on the car, it was REALLY tricky the first time I ever tried removing an airbag and I had to pull it off again because I didn't get it back in right so had an airbag light for a while. Its just not a fun part to mess with at all. But anyways I also struggled to find a good video and finally expanded out until I found one for like a Nissan truck but the wheel and airbag was very similar and finally somebody showed a GOOD inside view of what the retaining springs look like and do and it all made sense.
Be careful what you stick in there. I was desperately trying different things and at one point I stuck something like a bit extension for a drill in there that had a retention cutout near the end (the part that locks into your tool) and the airbag spring locked onto that and I could not get it out. Do NOT stick ANYTHING in those holes that is not pretty much smooth steel all the way to the end, nothing that can snag. I had to pull unbelievably hard to get that bit extension out and was very lucky not to have damaged anything. In the end two screwdrivers did the trick but it was still hard to figure out until you see a video showing the inside and how the springs work.
Seems like pretty good odds the wiring will already be in the clock spring, as others have set. Usually all these steering wheel buttons are just sets of resistor ladders so adding a couple more values probably not an issue, but they could have their own circuit maybe.

Yep AlfaOBD is just software, either in an app on your phone or on your laptop. On the AlfaOBD homepage they list the recommended bluetooth and wifi OBDII adapters that are known to work well with it. Seems like no matter which one you buy you also have to get one or two of these "adapter cables" (blue, grey) that map the correct pinouts from the OBDII port to the bluetooth adapter so it can access different parts of the CANBUS network. There seem to be a high speed and a low speed network, and one in-between or regular standard protocol that a cheap reader would be able to access normally. They cover this in detail on the AlfaOBD site too.
