How to add some text beside Header Toggle for Lovelace Entity Card?

Hi all,

I would like to add some text beside Header Toggle for Lovelace Entity Card, circled in RED as per screenshot below?
Capture

Is there any ways to achieve this?

Thanks.

There is no method to do this that I’m aware of.

It could be done. You’d have to design a custom card.

Noted.

But I have no idea how to design a custom card.
