Standalone app “warning” option

I am setting up the konnected as a standalone with esphome in home assistant but cannot toggle the “warning” beep on. I have the piezo buzzer set up and that does work. Can anyone assist with the warning beeps for the delay upon entering when alarm is armed? The delay is working but it’s silent. The link below shows a picture of the konnected set up with esphome and a toggle for warning. Mine is greyed out and not working.
