Turn off screen nest hub 2 when casting

I have a brand new nest hub 2 and I am using homeassistant cast. I noticed that the screen will no longer turn off automatically when casting. When showing photos it does.

Of course I can ask Google to turn it off and tap on screen to go back to the dashboard but that is not what I want.

So is there a way to do this automatically? Otherwise the screen must stay on as long as I am using the dashboard.

Thanks

hi,
u could try

service: media_player.turn_off
data: {}
target:
  entity_id: media_player.nesthub

Well then the casting will stop and the hub start to show photos. I would like the screen goes of while casting so I can return to the dashboard by tapping the screen
