I’m sorry, but I couldn’t find any Flux documentation on uploading a custom STEP file to a footprint. That likely means the feature isn’t currently supported in Flux. You may want to check the official docs or ask in the community:
Where can I find the asset manager
According to the Flux documentation, the Asset Manager lives in the Assets panel of the Inspector:
Assets – The Assets panel is where external files live, such as SVGs to use as custom symbols, or 3D models.
