Help identifying trim part

[Alli8]

Hello!
I'm trying to identify a small piece of interior trim as it's missing from my car and although it's not vital, I can see it. It's in the passenger footwell just where your feet are. I only want the small piece that is missing but it doesn't appear to be available on it's own.
I'm no stranger to an EPC as I'm in the motorcycle trade but this piece is proving elusive.  I think I may have found it (link to web page)

Also, I'm sure there is a nut or something missing too as in the hole there's an exposed stud. Anybody have any ideas?

Any help much appreciated, thank you.

The part doesn't exist, Toyota didn't design a cover to fit in the trim hole, the stud is designed exactly as you see the trim pushes over it then clips in on the front edge

How peculiar, just looks a little unfinished.  I shall endeavour to find something to cover the shiny stud so it's not so obvious.

Thank you!!

When I got my iQ (it was 9 months old) there was just a little rubber cap pushed over the stud, but it wasn't a full piece, it had been stuck on. Don't know if the previous owner had done it or not?

When I bought my IQ3 , I request the previous owner show me around before driving off.Whilst trying to take it all in he reached down and picked up a plastic clip.It did not register with me what it was, I took it and did not ask what it was.For a reason I do not know I disposed of it and regretted it ever since.It was however a hard plastic clip or cover for that shown.I think the rubber boot is adapted.
