After using a laser to remove a back glass there’s not a cat in hells chance I’d attempt it with hot air. UNLESS it’s been replaced before. Don’t bother watching YouTube videos as it’s not the original glass they’re removing as they are made to look easy. (Hence phones getting damaged by people thinking it’s easy) As said before, if you are going to try it then go easy and don’t force anything. You’d be better having a punch for around the camera lenses and a set of replacement mag safe magnets as they will come off and probably pull some coils off the wireless charger too. You might also rip the cable for the rear flash too.
Not being negative or trying to put you off. Just being honest about what could happen.
Good luck with it.
