Media Browser panel doesn't show up

Hi there,
I’m struggling with Media Browser panel or so. As far as I know, if correctly set up, there should be a panel on my Home Hassistant page or/and a “folder” icon on each media player entities. But there isn’t…:

This is a supervised HA version 2021.3.2, supervisor-2021.03.4, installed on a Debian machine.

This is my configuration:

configuration.yaml:

  media_dirs:
    media: /media/music

shell_command:
  mount_music_media_folder: mount -t cifs -o username=user,password=password,domain=WORKGROUP //192.168.1.104/HomeServer/Music /media/music

Plus I added an automation tha mount the samba share on each startup and it does work. In fact If I browse on docker folder I can correctly see my audio files are intended to be “browsable” on HA.

What am I missing here?
Anyone can help?

Thanks

Fixed.
I just didn’t put “media_source” in configuration.yaml

media_source:

That’s it.
