How do I use card mod to hide an entity?

I’m using browser mod to create a custom popup. I pre-allocated entities and will populate them when I call the popup. I want to hide the unused entities and I figured out some of it but can’t get it all. I can’t figure out how to hide the PRESS text…

Any suggestions?

Here is the current code and style is at the bottom…

          tap_action:
            action: fire-dom-event
            browser_mod:
              service: browser_mod.popup
              data:
                title: DEVICE CONTROL
                target:
                  device_id: dd902a1fafdfbdb69d60722ba32aa964
                content:
                  type: entities
                  entities:
                    - entity: '[[[ return variables.v_popup_entity1 ]]]'
                    - entity: '[[[ return variables.v_popup_entity2 ]]]'
                    - entity: '[[[ return variables.v_popup_entity3 ]]]'
                    - entity: '[[[ return variables.v_popup_entity4 ]]]'
                    - entity: '[[[ return variables.v_popup_entity5 ]]]'
                    - entity: '[[[ return variables.v_popup_entity6 ]]]'
                      card_mod:
                        style: |
                          :host {
                            color: transparent;
                            --paper-item-icon-color: transparent;
                            --primary-text-color: transparent;
                            --secondary-text-color: transparent;
                          }
