I'm trying to add sounds to the HAVPE and I'm not seeing direct instructions. Would the way to do this be to add audio wavs to Home Assistant and then play those before the announcement? I know this seems elementary but I don't have any audio media connected to HA so I can't even run a test without setting this up. I'd like to know that this is the current way of making HAVPE play sounds before an announcement before I go adding the sound infrastructure and connections to make this possible.
Lastly, did I miss a list of sounds/files that can already be accessed/played with HAVPE?
