Is this supposed to work?

I have assistant on TV, but I actually use a "smart" speaker, because it's always listening and so much easier to use.

if i say:

hey google, play XY on netflix on TV", does this generally work?

​

I does not work on my Philips PUS7304. So I am not sure if it's up to philips, or just a general limitation.

​

Additionally, I can't turn off/on TV. It also says that this is unsupported.

​

PS: flairs are really limited here. there is no right choice here.
