iPhone XS is child’s play, I genuinely can’t fathom why a repair shop (Apple store no less) couldn’t replace a screen on that device. 7 screws (including the pentalopes) and some heat is all you need. Takes 5 minutes of actual repair and another 2 or 3 to run the calibration software.
We used a hot plate that we could dial specifically to 70c so there was less risk of damaging the battery. Just leave the phone face down on it to bake, and after a few minutes the adhesive pulls apart easily.
