Dialogflow use cases

Im a big fan of Dialogflow (especially the ML part and the complex dialog you can achieve)
it’s quiete easy to integrate and confgure in Home Assistant, but i can’t find a real integration model.
I mean, using the Dialogflow interface i can have natural conversation about my home (getting status, switching on/off things, get data and so on), i can also integrate it in a text messenger (so i can “chat” with my home with telegram or messenger), but i cant find a way to easily have voice conversation with it from inside Home Assistant, for example, it would be nice to integrate Dialogflow, for example, in Assist. Or in any other voice assistant, since you can make complex dialogue with few lines of code!
Any suggestion?
Thank you
