Size of the layout using custom:decluttering-card

I’m experimenting with the custom:decluttering-card
It is making live easy. except I can not change the size of the card>
I’m using a custom:bubble-card
code:

type: custom:bubble-card
card_type: button
entity: binary_sensor.deursensor_woonkamer
show_state: true
show_last_changed: true
show_attribute: false
tap_action:
  action: none
button_action:
  tap_action:
    action: none
  double_tap_action:
    action: none
card_layout: large
columns: 2
rows: 1
name: woonkamerdeur
scrolling_effect: false
styles: >
  .bubble-button-background { background-color: ${state === 'on' ? '#1982C4FF' :
  ''} !important; opacity: 1 !important;}  .bubble-icon { color: ${state ===
  'on' ? '#1982C4FF' : 'white'} !important; opacity: 1 !important;} 
  .bubble-state { color: ${state === 'on' ? 'black' : ''} !important; opacity: 1
  !important;}   .bubble-name { color: ${state === 'on' ? 'white' : ''}
  !important; opacity: 1 !important;}
double_tap_action:
  action: none

I did create the template:

decluttering_templates:
  bubble:
    card:
      type: custom:bubble-card
      card_type: button
      entity: '[[entity]]'
      name: '[[name]]'
      show_state: true
      show_last_changed: true
      show_attribute: false
      tap_action:
        action: none
      button_action:
        tap_action:
          action: none
        double_tap_action:
          action: none
      card_layout: large
      columns: 2
      rows: 1
      scrolling_effect: false
      styles: >
        .bubble-button-background { background-color: ${state === 'on' ?
        '#1982C4FF' : ''} !important; opacity: 1 !important;}  .bubble-icon {
        color: ${state === 'on' ? '#1982C4FF' : 'white'} !important; opacity: 1
        !important;}  .bubble-state { color: ${state === 'on' ? 'black' : ''}
        !important; opacity: 1 !important;}   .bubble-name { color: ${state ===
        'on' ? 'white' : ''} !important; opacity: 1 !important;}
      double_tap_action:
        action: none

and using the template:

type: custom:decluttering-card
template: bubble
variables:
  - entity: binary_sensor.deursensor_woonkamer
  - name: Woonkamer

It is working.
Except the size of the card is different:
what I want:
image
what the template gives:


I changed the originall size with:

but this option is not available with the template card.
How to change the size of the template?
Thanks

I did find the answer:
I did add grid option to the code:

type: custom:decluttering-card
template: bubble
variables:
  - entity: binary_sensor.deursensor_woonkamer
  - name: Woonkamer
grid_options:
  columns: 6
  rows: 1
