Custom Event Log not showing

Goal:

To create my own custom log under Applications and Services Logs under the Event Viewer:

Code snippet:

.Net CORE 3.1

Host.CreateDefaultBuilder(args)
            .ConfigureLogging((hostContext, logging) =>
            {
              logging.ClearProviders();
              logging.AddConfiguration(hostContext.Configuration.GetSection("Logging"));
              logging.AddEventLog(
               eventLogSettings =>
                {
                  eventLogSettings.LogName = "My Log";
                  eventLogSettings.SourceName = "Dummy";
                });
              logging.AddConsole();
            });
// somewhere in my code, I use ILogger to write to the log

Configuration

    "Logging": {
      "LogLevel": {
        "Default": "Debug",
        "System": "Information",
        "Grpc": "Information",
        "Microsoft": "Information"
     }
   }

Problem:

While testin my developer machine, I see the log entry on the console, but I don't see the log in the Event Viewer. If I dropped the LogName, the log shows up in the Application Log on the Event Viewer. What am I missing?

Thanks!
