How to implement NUnit's NUnit.Engine.ITestEventListener

I would like to use NUnit.Engine.ITestEventListener within my test solution. Specifically I would be looking for end of the run <test-run...>.

I implemented the interface ITestEventListener within C# code within my test csproj. I set a break point within the interface. Within Visual Studio, I began debugging tests; never hit the break point. I then wondered if this is a NUnit Engine thing and MSTest knows nothing of it. Am I correct that MSTest will never hit my breakpoint with my class that implements ITestEventListener?

Alright lets try something else like writing out to the console log by using nunit3-console.exe to run the tests. My output within the interface never wrote a thing - everything else wrote out properly. So, what am I doing incorrectly?

using System;
using NUnit.Engine;
using NUnit.Engine.Extensibility;

namespace Learning.NUnitInterface
{
    [Extension]
    public class MyTestListener : ITestEventListener
    {
        public void OnTestEvent(string report)
        {
            Console.WriteLine("Hello there, here is your data: ");
            Console.WriteLine(report);
        }
    }
}
