Not seeing TV as an entity | Channel up and channel down by default

[FOSV]

As per the title, the TV is not seen as a device in home assistant, you can see it as a media player through the special card but it would be better to have it as a device in my opinion.
This brings me to the second problem, which is that you don't have direct control of the channels through special buttons in the media player.
I believe that the media player card does not support the channel changing function, so it would be nice to have an appropriate car with the main TV controls:

- power on / power off
- volume up / volume down
- mute
- channel up / channel down
- info
- Backwards
- play / pause / forward / backward
- arrows dial
- enter button
- source change

This would be a card I could draw on.

Thank you for your attention
