Newbie question about my Aeotec siren

I have a Aeotec6 siren. Using Hubitat I have a couple of contacts that I use to activate a doorbell sound in the siren. I am creating an automation and I have the contact there and I can select the siren and the option to turn it on, But how do I force it to play an individual sound It has 30 sounds and I want to us one of them In Hubitat I tell it to play sound 1. I assume I need to edit the Yaml but what would be the command?

Thanks alot
