Play audio to G4 Doorbell Pro or Instant? YAML

Is it possible to play an audio file, or even just a tone to either the Unifi G4 Instant or the G4 Pro doorbell?
I have an automation to unlock my August deadbolt with fingerprints from the G4 Pro, but no indication that the lock is open.
I have a TTS alert, but it’s loud. Maybe there’s a way to lower the volume?

Is there a better way to do this?
