Last update in Custom button Card

Hi everyone.
I need to show last updated state for motion sensors in my tablet view using the custom-button card.
What’s the way to do it?
I searched around but can’t obtain good results. I can show the last update just using the entities type card.

I want to display: name, state and the last update of the sensors.

This is the result for now. last update is shows as 0 seconds.

I tried to created a template sensor for each sensors

But the result is what shown in the first image.

Could anyone help me ?

Thanks
