Help identifying this piece?

See attached pic.

I want to replace this broken piece on the front of my ARE canopy.
I have no clue what it's called to even look up replacement piece.
Can you even buy a replacement piece for this?
What is the function of this piece?

Any help is much appreciated, thanks!

 

On older ARE MX tops, that was a functional window. The newer ones just have the piece of glass but no opening there, so it is a fully cosmetic piece that doesn't matter. You can clean it up and just have that spot be paint-colored, or replace it.

The only way to source that would be to go through your local ARE dealer, but it will be expensive since it's a tempered piece of glass.

 

I believe it's called a "vista window"
