Response Compression Example does not show anything useful

Description

https://learn.microsoft.com/en-us/aspnet/core/performance/response-compression?view=aspnetcore-8.0#azure-deployed-sample

I can see where the compressors are set up, but where are they shown being used?

The example is, with notes added
using Microsoft.AspNetCore.ResponseCompression;
using ResponseCompressionSample;

var builder = WebApplication.CreateBuilder(args);

//MY NOTE -- Here the compressors are set up
//but where are they used????
//Which responses are compressed, and which compression methods are used???

builder.Services.AddResponseCompression(options =>
{
options.EnableForHttps = true;
options.Providers.Add();
options.Providers.Add();
options.Providers.Add();
options.MimeTypes =
ResponseCompressionDefaults.MimeTypes.Concat(
new[] { "image/svg+xml" });
});

var app = builder.Build();

app.UseResponseCompression();

//MY NOTE -- Do any of the following use compression?
//If so, how, and which compression is used?
//Thank you....

app.Map("/trickle", async (HttpResponse httpResponse) =>
{
httpResponse.ContentType = "text/plain;charset=utf-8";

for (int i = 0; i < 20; i++)
{
    await httpResponse.WriteAsync("a");
    await httpResponse.Body.FlushAsync();
    await Task.Delay(TimeSpan.FromMilliseconds(50));
}

});

app.Map("/testfile1kb.txt", () => Results.File(
app.Environment.ContentRootFileProvider.GetFileInfo("testfile1kb.txt").PhysicalPath,
"text/plain;charset=utf-8"));

app.Map("/banner.svg", () => Results.File(
app.Environment.ContentRootFileProvider.GetFileInfo("banner.svg").PhysicalPath,
"image/svg+xml;charset=utf-8"));

app.MapFallback(() => LoremIpsum.Text);

app.Run();
