How to replace power button

I saw that ifixit sells original Google Pixel (not the XL) power buttons, but there’s no guide on it. On top of that, I couldn’t find one anywhere on YouTube. If possible, could someone make a guide on how to replace the power button? Or at least show me how to? As old as my phone is, I still want to use it a little bit longer before I commit to buying a new phone. Currently, my screen and battery are broken, and I’m seeing to replacing them soon as not everything I want is backed up. I want to be able to fix every issue my phone’s been giving me since late 2018, but I don’t want to seem like I’m telling you how to do your job or that I’m entitled anything. I just really enjoy seeing the community help each other, and I find it hard to believe that I’m the first person to say something about the faulty power button since the phone’s launch in late 2016. On a sidenote, most teardowns of the original Pixel (not the XL; I only found two) never touched the power button, so I’m lost on that end as well. I’d highly appreciate it if somebody could make a guide. This is on a much lower priority than the power button, but if somebody could inform me as to where the bluetooth is located within the phone would be helpful as well. I know I’m asking a lot, but the bluetooth thing is more of a want than a need, unlike the power button. Thank you to whoever decides to reply, as I will be at the mercy of your advice.
