Need help with Custom button card to control one entity with short press and another with long press

Hi All,

I have the following installed and I am looking to have one button where I can control a switch with the short press and get the “more info” for a bulb on the long press. this way I can control the switch on the wall with the short press and set the brightness and colour temp with a long press… but I have no idea where to begin to make this happen.

i’ve tried to add an entity_id: for the bulb under the long_press: on the button but no joy.

first is it possible?
second… how ?

thank you for your help
