State attribute in a lovelance card

The entity “sun.sun” has many attributes. I would like to show a few of them on the dashboard.
Works fine as template:

{{ state_attr(‘sun.sun’, ‘next_rising’) }}

returns

2022-03-09T06:18:50.621499+00:00

I did not find explanations on how to do that in a lovelance card.

Entities cards support attributes https://www.home-assistant.io/lovelace/entities/#special-row-elements

There are examples using the sun entity attributes lower down on the page https://www.home-assistant.io/lovelace/entities/#other-special-rows

That’s exactly it!
Now i need to find out how one can format the timestamp… will search … :thinking:
