Inline keyboard also appears on done message

Hi all,

I’m playing around with alerts and inline keyboards.
When the alert fires, I get the message which also contains two buttons: turn off and acknowledge

alert:
  heater_office_on:
    name: Heater Office is On
    done_message: Heater Office is turned off, thanks!
    entity_id: switch.shelly_1pm_04
    state: 'on'
    repeat:
      - 15
    can_acknowledge: true
    skip_first: true
    notifiers:
      - telegram
    data:
      inline_keyboard:
        - 'Acknowledge:/acknowledge_4'
        - 'Turn Off:/turn_off_heater_4'

the two options of the inline keyboard are both handled by an automation, which either turns off the heater or turns off the alert.

alias: 'Telegram Callback Handler'
id: 'telegram_callback_handler'
trigger:
  - platform: event
    event_type: telegram_callback
action:
  - choose:
      - conditions:
          - condition: template
            value_template: "{{ trigger.event.data.command == '/turn_off_heater_4' }}"
        sequence: 
        - service: switch.turn_off
          entity_id: switch.shelly_1pm_04
      - conditions:
          - condition: template
            value_template: "{{ trigger.event.data.command == '/acknowledge_4' }}"
        sequence: 
        - service: alert.turn_off
          entity_id: alert.heater_office_on
    default:
      - service: notify.telegram
        data:
          message: 'I can''t choose...'

This all works fine, except that I get the inline keyboard on the done message as well… Is there a way to avoid that?
