Casting booksonic to Google Home Minis


I am planning on using a booksonic server to stream audiobooks, and I would like to use HomeAssistant to enable this stram on a google home mini speaker or group of speakers.

Could someone help me (or direct me to some materials about) how to use HomeAssistant to control audio stream from self-hosted server to be played at google home minis that are discovered by Home Assistant?

any luck with that topic?

Any luck with this?
