Trim Piece - where does it go ?

[BriteBlue]

I opened the left/rear door of my 2018 Civic sedan & this black plastic trim piece fell on the ground.

I looked & felt all around the door & jamb & just about everything below the belt line where the trim is black. Even looked around the front door area in case the piece bounced its way backward but no luck.

It only has a few numbers & letters on it.
RR, which I presume means rear
L, which I presume means left
>PP-TD10<, which means nothing to me
TEG, which also means nothing to me

It obviously fits an inside corner which is pretty much a 90° angle.

Any suggestions what it is or where it goes would be appreciated.
Thanks
