How do you cast a media via google home voice assistant to chromecast?

Question

I have a video streaming web application like netflix. I am able to cast a media on my webapp to my TV. I would like to use google home to cast the media using its voice assistant. For example: 'Hey Google, play "Get Out" from <"my-weapp-name">'. This should play Get Out on my TV via a chromecast device that is plugged into my TV. How do I use google action and/or dialogflow to do this?

Answer 1

Right now there is no public API that can be used for casting media through the Google Assistant.
