I don’t know where consciousness is but I think if we accept that you can simulate a brain exactly that doesn’t prove consciousness of a model as consciousness is a metaphysical concept really

This seems like a different topic from whether consciousness "uses" the brain?

But I will point out we don't have a way to prove anything is conscious, not even a human.

Consciousness appears to be a biological phenomenon, but so too are metabolism, reproduction and evolution. Are these also metaphysical concepts?

Consciousness does not appear to be biological, that is an opinion and a highly debated one

Where does it appear outside of biology?

Where does consciousness appear in biology? It’s a philosophical/metaphysical concept so far as I can tell

The one thing that I think all philosophers agree on is that the only confirmed cases of consciousness discovered so far are biological. They are divided over whether there is anything fundamentally more metaphysical about it than other biological phenomena (with Dennett having been the best-known dissenter, though he has many successors), and the debate has been going on without resolution for centuries, if not millennia.
