Invalid Username when getting currently playing track

[PxrpleDemxn]

Hi, I am trying to get my currently playing track but unfortunately I am getting "Invalid Username" in console... What should I rewrite or add? Thanks
`
var config = SpotifyClientConfig.CreateDefault().WithAuthenticator(new ClientCredentialsAuthenticator("CLIENT_ID", "CLIENT_SECRET"));

    var spotify = new SpotifyClient(config);
    var current = new PlayerCurrentlyPlayingRequest(PlayerCurrentlyPlayingRequest.AdditionalTypes.Track);
    var currentlyplaying = await spotify.Player.GetCurrentlyPlaying(current);
    IPlayableItem s = currentlyplaying.Item;
    if (s is FullTrack track)
    {
        Console.WriteLine(track.Name);
    }`

It's not possible to use ClientCredentialsAuthenticator in combination with Player.GetCurrentlyPlaying. ClientCredentialsAuthenticator can not access user resources
