Using same instance to pop up notification (click on component)

Development

Hello,

I have own ui component, but if I click on component, pop up doesn’t use same data. How should I ensure the same instance for pop up window?

Configuration my component:

 customize_glob:
    sensor.slider_mon:
      custom_ui_state_card: pf-progress-slider

frontend:
  extra_html_url:
    - /local/custom_ui/pf-progress-slider.html

 sensor:
   - platform: template
     sensors:
      slider_mon:
        value_template: slider_mon

How to make singleton instance?

Thank you.
