Automation template - Person who triggered the automation

Hi!

I’m not sure if it is possible, but can you set in an automation a template to get a message regarding the user who triggered the action? What i want to achieve is that if the alarm is triggered and a person dissarms it, I get a message with the name of the person who disarmed it.

- id: '1597270957787'
  alias: Disarm alarm notification
  description: ''
  trigger:
  - entity_id: alarm_control_panel.alarm
    from: triggered
    platform: state
    to: disarmed
  condition: []
  action:
  - data_template:
      message: 'The alarm was deactivated by xxxxx'
      title: '*ALARM DEACTIVATED*'
    service: notify.telegram
  mode: single

Looking for something similar, did you work this out in the end?

No, I’m sorry, I desisted after too many failed attempts to create a template for the sensor attribute, but my Jinja2 skills are very limited
