Insert bubble-card into custom button-card

hi there, been messing with this and I am unable to achieve this

this is a test setup, I want to have a button whose action would be a popup card. In my room there are four blinds, so the button will be a mdi:blinds icon, on tap acion it will navigate to a hash defined as per manual of custom bubble card.
