NLog.Web: aspnet-sessionId not working for Asp.Net Core (.Net 4.7)

We are trying to use aspnet-sessionid in an ASP.Net core application (.net version 4.7) and nLog is not showing it in the logs at all.

We tried with multiple different configuration values, but none produce any output.

Is this supposed to be working in ASP.Net Core and .Net 4.7?

For reference:

In Startup.cs

        public IServiceProvider ConfigureIoC(IServiceCollection services)
        {
            var container = new Container(new RuntimeRegistry());
            container.Configure(config => config.Populate(services));
            services.AddSingleton<Microsoft.AspNetCore.Http.IHttpContextAccessor, HttpContextAccessor>();
            return container.GetInstance<IServiceProvider>();
        }

        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
        public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
        {
            //loggerFactory.AddConsole(Configuration.GetSection("Logging"));
            //loggerFactory.AddDebug();
            loggerFactory.AddNLog();
            env.ConfigureNLog("nlog.config");
            app.UseMvc();
        }
