Trouble applying material after import from OnShape

Is there a trick to apply materials (for appearance) after importing from OnShape? I’ve worked with Create… there I just need to drag and drop one of the Omniverse supplied materials onto the object or select it in properties and it just works. I try the same thing in Isaac Sim and the appearance doesn’t update. Although the materials do update in the property menu. I tried toggling the “Weaker / Stronger than Descendants” but that didn’t change anything.
