Rubber piece found in back seat

[violinist22]

I just discovered a piece of rubber on the back seat of my Telsa (5 seater). Car was purchased at the end of June and no one has sat back there yet. Just curious if anyone can identify this (see pictures) and where it belongs. It's approx. 4" x 2". I sent a note to the SC as well.

Thats a squeegee. Thats what they use to install ppf. Have you had any done? The installer may have left it there.

Yes, that's it. I had XPEL Ultimate added. Thanks so much!
