Can’t find this trim piece anywhere

Plug your VIN in over at GMPartsGiant and have a look. Maybe try GMPartsDirect as well, they have diagrams.

I’ve looked through those diagrams up and down dozens of times on GM Parts Giant. I’m 99% sure it can’t be purchased. Called local dealer who sent me a very detailed diagram from EPC and unfortunately as shown below no.23, they told me that it’s not sold individually, only part of the glass.
