Alarm code_format: any (string and not number)

Hi everybody out there.

I’d like to use a string instead of a number to unlock my alarm.
According to documentation seems possible:
https://developers.home-assistant.io/docs/en/entity_alarm_control_panel.html


41

The same looking to the changelog of version 0.85

But I got error when adding “code_format: any”:

- platform: manual
  name: alarm
  code: !secret alarm_control_panel
  code_format: any
  pending_time: 30
  delay_time: 20
  trigger_time: 4
  disarmed:
    trigger_time: 0
  armed_home:
    pending_time: 0
    delay_time: 0

The same if I try to add it on the panel card:

entity: alarm_control_panel.home_alarm
states:
  - arm_away
  - arm_home
type: alarm-panel
code_format: any

Thank you!!
