Question about voice notifications

So I use IOS with shortcuts, Assist and a Homepod Mini to use voice activation with my setup and it works well. Is there a way I can get notifications for HA doing text-to-speech or something like that? For instance, I sometimes leave my refrigerator door open slightly. Can I have Siri or my HA tell me the refrigerator is open?

Like using TTS notifications with the Companion app?

Something like that, but I’d like the voice to come out of my Homepod Mini.
