_server.AuthorizationCodeReceived isn't raised when receiving an access token

[NielsKoomans97]

I'm curious what's going wrong.

I use Visual Studio 2022 community edition on Windows 11 latest build. I have chrome, edge and brave installed.

` private async void Form1_Load(object sender, EventArgs e) { _server = new EmbedIOAuthServer(new Uri("http://localhost:5543/callback"), 5543);

        _server.AuthorizationCodeReceived += _server_AuthorizationCodeReceived;
        _server.ErrorReceived += _server_ErrorReceived;
        _server.ImplictGrantReceived += _server_ImplictGrantReceived;

        await _server.Start();

        var request = new LoginRequest(_server.BaseUri, "16d40a7f986d49a3991c32934a1b4f50", LoginRequest.ResponseType.Code)
        {
            Scope = new List<string> { Scopes.UserModifyPlaybackState, Scopes.UserReadPlaybackState }
        };

        BrowserUtil.Open(request.ToUri());
    }

    private async Task _server_ImplictGrantReceived(object arg1, ImplictGrantResponse arg2)
    {
        listView1.Items.Add("Client");
    }

    private async Task _server_ErrorReceived(object arg1, string arg2, string? arg3)
    {
        listView1.Items.Add("Error");
    }

    private async Task _server_AuthorizationCodeReceived(object arg1, AuthorizationCodeResponse arg2)
    {
        await _server.Stop();

        ClientConfig = SpotifyClientConfig
            .CreateDefault();

        listView1.Items.Add("Authenticating");

        var response = await new OAuthClient(ClientConfig).RequestToken(
            new AuthorizationCodeTokenRequest(
                "16d40a7f986d49a3991c32934a1b4f50", "6f652f2b518243c3aecf86db25891323", arg2.Code, new Uri("http://localhost:5543/callback")
                )
            );

        throw new Exception($"{arg2.ToJson()}   {response.ToJson()}");

        Client = new SpotifyClient(response.AccessToken);

        listView1.Items.Add("Client");

        var queue = await Client.Player.GetQueue();

        foreach (var item in queue.Queue)
        {
            var lvi = new ListViewItem();
            lvi.Tag = item;
            lvi.Text = item.ToJson();
            listView1.Items.Add(lvi);
        }

        listView1.Items.Add("received");
    }`

As you can see, I try to receive an access token here to use for access to the queue, and to be able to add premium tracks to the queue.

For some reason, at Form1_load, _server.AuthorizationCodeReceived += _server_AuthorizationCodeReceived isn't raised when the authorization request has been successfull. I've tried with a different port, various browsers, even checked if the ImplicitGrantReceived event wasn't raised instead. None of the registred events do anything, at all.

Am I missing something, is the browsers I tried with, or is the library broken?
