Correct definition of tv remote switch in alexa.yaml?

I have a two entities in HA from my panasonic integration:
remote.65ex730_series state on/off
media_player.65ex730_series state on/off and some more
I try to use alexa to switch the TV per voice on and off, but alexa didn´t find a device. ( but many others are working )
I dont now how to define a remote or TV in the alexa.yaml.

Some of my test with alexa.yaml

filter:
  include_entities:
    - remote.65ex730_series

  entity_config:
    remote.65ex730_series:
      name: Television
      description: Versuch den Fernseher über die Panasonic Integration zu schalten
      display_categories: TV   or  REMOTE   or SWITCH    #  nothing is working

Any sugesstions are welcome.
Thanks in advance,
Andreas.
