Props configuration of popover secondary widget

Hi
I defined the child widget properties directly from the main widget as described in this thread:
[Accessing a Custom widget properties from a another Custom widget prop window - #8 by Keeef]
but i don’t know how to call these properties when the widget is called via f7-popover

    - context: pagewidget
      label: fireplace widget
      name: widget_name
      required: false
      type: TEXT
      groupName: widget
    - context: props
      description: Props for the widget
      label: Widget Props
      name: widgetprops
      required: false
      type: TEXT
      groupName: widget
  parameterGroups:
    - name: widget
      description: Popover Widget
- component: oh-link
  config:
    action: popover
    popoverOpen: .fireplace
    style:
      height: 22px
      left: 15px
      position: absolute
      top: 90px
      width: 22px
      z-index: 2
    tooltip: fireplace
    visible: true
  slots:
    default:
      - component: f7-popover
        config:
          class: fireplace
          style:
            --f7-popover-border-radius: 8px
            --f7-popover-width: 495px
        slots:
          default:
            - component: =props.widget_name
              config:
                ???????????????????????????

for now the only working way would seem to be setting the properties one by one as follows,

          - component: f7-popover
            config:
              class: fireplace
              style:
                --f7-popover-border-radius: 8px
                --f7-popover-width: 495px
            slots:
              default:
                - component: =props.widget_name
                  config:
                    header: =props.widgetprops.header
                    fgcolor: =props.widgetprops.fgcolor
                    fgcolor2: =props.widgetprops.fgcolor2
                    temperature: =props.widgetprops.temperature
                    targetTemperature: =props.widgetprops.targetTemperature
                    fireplace_power: =props.widgetprops.fireplace_power
                    start_stop_lights: =props.widgetprops.start_stop_lights
                    heat_low_hight: =props.widgetprops.heat_low_hight
                    consumption_total: =props.widgetprops.consumption_total

but I would like that all the properties and values to be automatically and dynamically defined by the widgetprops setting, so that if the child widget changes there is no need to change the main widget.
i have seen that setting a text label title: =props.widgetprops, it returns a json obj like this

{"header": "Fireplace", "fgcolor": "orange", "fgcolor2": "gray", etc....}

I don’t think this is possible, at present. The config object of the component is not run through the expression parser so you can’t put an expression in there.
