Possible help with micro soldering project?

Have a older Nexus 5 cellphone that I have rebuilt several times since 2013. Phone still works and runs well and I really enjoy the android software and “experience”. Long story short I had been having problems the last year or so with the power button remaining stuck on. Button finally froze in the power up/on position putting the phone into a bootloop. I have managed to unsolder the old button from the board, but not sure if I have the skill or tools for installing the new power button. Thanks again
