I did some searching and I think these might be the center caps off a 2022+ Tundra 1794 edition. The part number I found is
PT998-35221-3S. I have not ordered them myself, so I cannot confirm the part number is correct.
I'm interested in more detail or pictures of how it works in the second row area. I think you said it can be used with the second row seats, how does that feature function?
