How to remove iPhone 14 back glass microphone?

I have heard that the flash and microphone attached to the back glass is serialized and you need the original one to replace the back glass or else it won't save photos with the flash turned on. is this still true? and if so, how do you remove the microphone attached to the back glass??? i have been going at it for days with isopropyl, heat, and various prying tools and it will not budge. is it welded or something? because at this point i have tried everything and am just about ready to give up and deal with getting chewed out by my client because it won't save photos with the flash turned on and all i can say to him is sorry.
