How to manually set state to alarm panel?

Hi
I can not find a way to skip pending on manual Home Assistant alarm panel. I need to set state ‘triggered’ instantly, skipping the pending part
I need this for one automation, but in other scenarios I use pending, so I can not just totally delete it
Is it possible just to set ‘triggered’ state to it via scene?
This did not work out:

- name: Alarm
  entities:
    alarm_control_panel.ha_alarm:
      state: triggered
      code: '0000'

I need this for firing from smart speaker. So if there is somebody at home and he needs to turn on alarm - he would say it to smart speaker and alarm would immediately fire
I did that manually (without alarm panel), but I need one way to turn that off from app, and the best way would be via alarm panel

Any ideas out there?
