You should be able to either:

1- Use a usd file import node and import it onto sops, making sure you unpack into Polygons.

2- If its loaded as a reference or already in your scene graph, use a sopmodify node and again unpack it to polygons so you can tweak it.

It has to be connected to something for it to work. This node is also extremely finnicky and causes a lot of crashes for us so beware. You can always drop a surface unlit shader and connect that to the output, very annoying and slow to work with but at least it doesn't crash 50% of the time.

Id assume that if you author asset type primvar then it should be managed like any other asset path in LOPs

If you are authoring it from SOPs you can do that in SOP Import and specify your attrib in Asset Path Attributes instead of keeping it just as string

That was it! Thank you Tomas!
