Automation Telegram Bot Duplicate

Hi,

I have a automation and script to open my frontdoor for multiple users.
I want a picture to be sent to the person who gives the /frontdoor_unlock command in telegram bot and to myself.
But when I open the door by myself I get the picture twice.
How can I prevent a duplicate picture when opening the frontdoor by myself?

scripts.yaml

unlock_frontdoor:
  alias: Frontdoor Unlock
  sequence:
  - data:
      entity_id: switch.frontdoor_lock
    service: switch.turn_on
  - delay: 00:00:02
  - data:
      entity_id: switch.frontdoor_lock
    service: switch.turn_off
  - data:
      message: Frontdoor unlocked
    service: notify.donald

automation.yaml

- id: '1550932164881'
  alias: Frontdoor Unlock via Telegram Chatbot
  trigger:
  - event_data:
      command: /frontdoor_unlock
    event_type: telegram_command
    platform: event
  condition: []
  action:
  - data:
      message: Unlock Frontdoor via Telegram Chatbot
    service: script.unlock_frontdoor
  - data:
      entity_id: camera.hallway
      filename: /tmp/camera-hallway.jpg
    service: camera.snapshot
  - data_template:
      caption: Unlocking Frontdoor for {{ trigger.event.data["from_first"] }}
      file: /tmp/camera-hallway.jpg
      target: ['{{ trigger.event.data.user_id }}',!secret telegram_id_donald]
    service: telegram_bot.send_photo

Any help would be appreciated!
