How do I replace screen bezel frame iPhone 5?

I was trying to take the screen out to access the battery, unfortunately only the screen and the digitizer came out and the screen plastic bezel got broken. Ive seen the piece is sold online as front screen bezel, digitizer bezel, screen bezel and similar names but I havent been able to find a manual or video showing how to replace it.

The screen assembly also comes with this bezel but I dont need the whole thing, just the front bezel replaced, any help will be appreciated, thanks
