How to notify on all logged errors?

Configuration

I have the following automation to notify on errors in the logs:

alias: Notify logged errors
description: Notify logged errors
triggers:
  - event_type: system_log_event
    event_data:
      level: ERROR
    trigger: event
conditions: []
actions:
  - delay:
      hours: 0
      minutes: 5
      seconds: 0
      milliseconds: 0
  - action: notify.mobile_devices_admin
    data:
      message: |
        ERROR occured in the logs: {{ trigger.event.data.message }}
      title: ERROR occured in the logs!
mode: single

I now realized that this seems to only notify errors of the HA core component. How do I need to modify this alert to notify for all errors that I see in the HA logs?
