Can't get Netflix/PS4 to respond to PS4 key integration

I’m just trying to pause netflix by pushing the big button in the middle of the controller (called PS i guess) but it’s not really doing anything for me.

I tried starting the ps4 media player (turn on) then issuing the command. Nothing.
Not sure what i am missing here.

Could someone share their config how you send commands? Maybe i need to reset the integration.

Thanks all.
