Surround Mirror access cover for Blind Spot

[bill-e]

The other day I had an encounter with some falling cables in a snow storm, A cable wrapped around my mirrir and caused the plastic cover which provides access to the outsise Temp probe come loose and disappear.

A quick liik online doesn't show it for sale anywhere

Does anyone know where I might buy the part or does anyone have a broken 2020 Driver's side surround mirror which could be sold for parts?

This is not a blind spot antenna, it’s the outside temperature sensor.
