How to find the exact model used by another artist

Raymond40k

There is this artist that makes 3D art using Daz 3D, they may have downloaded their models for their art judging by their comments and posts about the program, but I do not really know from which website or community.
I tried using reverse image but found nothing and used AI, but it only managed to find another model that was not clearly the one I wanted. It suggested that I should ask the Daz community for help tracking down this model. I want to know where they got this model from, but the artist has been inactive for half a year, their other post also suggests that they are very busy IRL, so I feel that I will get a slower response if I try asking.

I do not know if it is allowed to ask for help tracking down or identifying a model, but I want to try.
