Using a homepod as a speaker via HA

Hi. I have several homepods in the house, and I’d like to use music assistant to stream music and maybe radio to these Homepods. I can find no information on how to do this because I can find no information on how to properly connect the homepod to HA. “Use Homekit Bridge” is not the answer I’m looking for because there seem to be no instructions on HOW to use homekit bridge to connect the thing. I’ve tried it several different ways, and nothing works. Does anyone know of any way to do this?

You can use music assistant to send music via airplay, but the bigger question is why isn’t the native apple tv integration media player exposed in music assistant?

Also, the airplay provider does not appear to sync player state and play queue information with what is being played via native ios/home player.
