Can not connect to a hub that has Authorize property

[MohamadTahir]

my dontet project has a hub that requires users to have a valid jwt token, my configuration is

HubConnectionBuilder()
      .withUrl(
        "$_serverUrl/hubName",
        options: HttpConnectionOptions(
            accessTokenFactory: ()=> "",
            logger: Logger("SignalR - transport"),
            requestTimeout: 50000,
            logMessageContent: true,
            )),
      )
      .withHubProtocol(MessagePackHubProtocol())
      .withAutomaticReconnect()
      .configureLogging(Logger("SignalR - hub"))
      .build().connect();

but I am getting the following error.

I am sure the connection is failing because of the Authorize Attribute, removing the attribute from the hub solves the problem, but I need the authorize tag.

options.Events = new JwtBearerEvents
    {
        OnMessageReceived = context =>
        {
            var accessToken = context.Request.Query["access_token"];
            var path = context.HttpContext.Request.Path;
            if (!string.IsNullOrEmpty(accessToken) && path.StartsWithSegments("/hubs"))
            {
                context.Token = accessToken;
            }

            return Task.CompletedTask;
        }
    };

Add jwt bearer event and map the access_token gotten from query to context, since Authorize attribute of signalr does not get data from http request like in a controller.
