2016 Fiat 500x Easy Right Side Mirror Turn Signal Cover

I recently purchased a 2016 Fiat 500x Easy, but the Right Side Mirror Turn Signal Cover is broken. The signal still works/blinks as normal, but the cover is gone. I've been Googling and searching, but cannot find this part. Can anyone help me track one down or point me in the right direction?

Attached is an image of what I need. It's the piece inside the green.
Any help would be appreciated.
Thanks,
Chris
