Can't get thumbnails to load using GlobalSearchWidget

At this point I’m not getting any errors or warnings in the console:

self._task_manager = task_manager.BackgroundTaskManager(self)

        globalSearchWidget = GlobalSearchWidget(self)
        globalSearchWidget.set_searchable_entity_types({"Asset": []})

The search lists assets, is filterable, etc, but I get no thumbnails:

My console output is:

2023-07-10 21:03:47,984 [   DEBUG] [PROXY] ...done

Is there anything else that needs to be done for thumbnails to work?

UPDATE: If I remove the set_searchable_entity_type({“Asset”: }) I get thumbnails, (but obviously not the filtering I need)

UPDATE UPDATE: Correction, those weren’t assets I was seeing with thumbnails. It seems versions get thumbnails, assets get nothing. I cleared the cache to no change
