How to get access to anti dust earpiece mesh?

I just bought an lcd assembly to replace the screen on my 5t but the replacement has come without the earpiece anti dust mesh.

I still haven't started the repair yet so I still have the old screen with the mesh still in there. I was wondering can I actually get access to the mesh without taking the glass off the midsection? Do I even need it in the new screen?

Thanks in advance for anyone who knows anything. Can't find any answers about this anywhere. Seems like everyone forgets about this small part.
