Show attributes of automations

I have created an automation that switches on the pump for the garden irrigation when the button ‘wasser_30_min’ is pressed, runs it for 30 minutes and then switches it off again.
I found out that the information whether the automation is running is in the attribute ‘current’.
The automation works so far. However, I would now like the button to show that the automation is running and how long it is still running. How would you go about it?

alias: Gartenbewaesserung_30min
description: ""
trigger:
  - platform: state
    entity_id:
      - input_button.wasser_30_min
condition: []
action:
  - type: turn_on
    device_id: 81db6e7380ebf1d623bb57f6a88d4de3
    entity_id: switch.gartenpumpe_einschalter
    domain: switch
  - delay:
      hours: 0
      minutes: 30
      seconds: 5
      milliseconds: 0
  - type: turn_off
    device_id: 81db6e7380ebf1d623bb57f6a88d4de3
    entity_id: switch.gartenpumpe_einschalter
    domain: switch
mode: single

What button?
Automation state/attributes are like any other entities…

Oh, I wasn’t clear in my description.
I would like to be able to start the automation in my dashboard with a button. I would like to see on the button how long the automatin is still running and whether it is running.
