Chakra UI Card

Hay how are you ?

I’m new in Figma (so sorry if my question is dumb)

I have to realise a Chakra Card (for a Web site Dev in Chakra)
So i use the “Chakra UI Figma Kit” that i uploded to my library, but i cant edit this card.
(To add image or Btn.)

So how we can edit a card ? and if it’s impossible i have to do create my own card ? (but will not the same like Chakra UI kit…)
