A piece of plastic trim fell off of my 1996 es300, yet I cannot, for the life of me, figure out what it's called in order. It's making it difficult source a replacement.

I still have the original part, but most of the clips are broken or missing. Ultimately, I just need to reattach the panel, so my hope is that identifying it will help narrow down my options.

Help! What is the technical name for this? (not my actual car pictured)
