How do you replace back camera glass?

Linked are a Youtube video on how to replace the back glass for that specific model, but doing a quick scroll through it I'd definitely recommend using the technique and tools shown in the IFixIt link that shows a breakdown of the P30 Pro as using the long, bare razor blade like they did is dangerous to both you and the phone itself.

You're responsible for your own device, repairs, and safety but best of luck and let me know if you get that replaced successfully!
