That is not a supported repair. And if you’ve ever seen people try it you’d not spend a dime for it. The display glass at the factory is sealed in strict clean room conditions, under vacuum using special adhesives.
Believe a random YouTube video if you wish, but you cannot remove cleanly, nor reapply the glass screen properly. I have seen the aftermess of a couple of people who have tried this at various times - it’s a disaster. And if you do so, Apple may refuse any further service afterwards either in or out of warranty.
If you have Apple (or an Apple Authorized service provider) replace the display, you will continue any remaining original warranty, or receive 90 days warranty on the part and work (whichever is longer).
Ask the hack whose going to rip apart your OEM sealed display what kind of warranty they offer? Attempting such a repair seems extraordinarily penny wise and pound foolish to me.
