I made a custom block model in blockbench for my modpack, for some background its a model of a small rock that you'll be able to pick up.
But, I'm not sure how to actually set the model to be used. I tried searching up what to do in the blockstates json in order for the model to load, but I couldn't really find anything and I'm stuck with the missing texture.

How would you set the blocks' blockstate json to take a custom model?
