SignalR with openiddict user claims with react

I'm currently working on a project with a react client and asp.net server. I was tryin to add authorization to the signalR requests in the server using the existing claims that the user use in the api but I couldn't wrap my head around it. I managed to receive the access token from the client but I don't understand how I can receive Context.User.Claims.

I'm adding the client signalR connection and a try from the server:

client:

let newConnection = new HubConnectionBuilder()
      .configureLogging(LogLevel.Debug)
      .withUrl(`${URL}${HubUrl}?access_token=${'SampleAccessToken'}`, {
        // a token factory for the server, not sure why we need it
        // accessTokenFactory: () => 'SampleAccessToken',
        skipNegotiation: true,
        transport: HttpTransportType.WebSockets,
      })
      .build();

Server:

public async Task JoinJobGroup()
    {
        var httpContext = Context.GetHttpContext();
        var tmp = httpContext.Request.Query["access_token"];

        // TODO: Receive the claims form tmp or other solution
        // TODO: Check if claim is valid for operation
        
        await _Context.Groups.AddToGroupAsync(Context.ConnectionId, "JOB_GROUP_NAME");
    }
