Decluttering card doesn't seem to allow hold_action

I’m using the custom:decluttering-card to create a status tile in Lovelace and it doesn’t seem to be taking setting the tap or hold action.
Here’s the definition (Note that I’m using the custom:button-card as well).

# card to show various (on/off) modes

           }
            return ``

and here’s how I call it in my ui-lovelace.yaml file:

              - type: 'custom:decluttering-card'
                template: mode-thing

                  - thing_icon_off: 'mdi:walk'
                  - thing_name_off: 'about'
                  - m1_show: 'true'

                  browser_mod:
                    command: call-service
                    service: browser_mod.popup
                    service_data:
                      deviceID: this
                      title: Modes
                      hide_header: false
                      card:
                        type: entities
                        entities:
                           - entity: input_boolean.in_bed
                             name: In Bed
                           - entity: sun.sun
                             name: sun position
                           - entity: switch.presence_simulation
                             name: mimic lights

It only does this with the custom:decluttering-card implementation. (If I create a “hard-coded” card like the following, hold action works.

Here’s the Lovelace coding for that card:

                  browser_mod:
                    command: call-service
                    service: browser_mod.popup
                    service_data:
                      deviceID: this
                      title: Modes
                      hide_header: false
                      card:
                        type: entities
                        entities:
                           - entity: input_boolean.in_bed
                             name: In Bed
                           - entity: sun.sun
