Where do these go?

I found these 2 plastic covers in the back of the LC200 when I bought them but have no idea what they do or where they go. Help, please.

As mentioned, they go on the back of the 3rd row seats. Watch at the 3:52 mark in the video. Shows how they come off and what holds them in place:
