The C425 camera and TD25 Doorbell say "Works with Google Home", but where do I find exactly what that means? 

I have linked my Tapo account to Google Home and I see C425 camera in Google home, but I cannot view the video, it says "This video stream can't be viewed here. If you have a smart display or Chromecast, you can ask the assistant to stream it there."

The TD25 doorbell does not even say that.  

There are no starters (triggers) for the C425, and the only one for the TD25 is "Doorbell Rings",  and there are no actions for either.

So what can you do with these using Google Home?
