Entity objects in the picture glance card

Continuing my quest to better understand the picture glance card.

The documentation (https://www.home-assistant.io/lovelace/picture-glance/) mentions that for 'entities' either entities or entity objects can be used. In the case of entity objects additional details can be provided such as attrbutes etc.

However I can’t find any examples of what an entity object looks like. Could someone please point me to the right direction?

Found this:
If you define entities as objects instead of strings (by adding entity: before entity ID), you can add more customization and configuration.
