Karma: Cannot load browser "EdgeHeadless": it is not registered! Perhaps you are missing some plugin?

Question

I want to run karma without opening the browser, and I'm getting an error and I don't know how to make it work.

Windows, Angular, Karma, Jasmine, and Edge

karma.conf.js

module.exports = function(config) {
  config.set({
    basePath: '',
    frameworks: ['jasmine', '@angular-devkit/build-angular'],
    plugins: [
      require('karma-jasmine'),
      require('karma-chrome-launcher'),
      require('karma-edge-launcher'),
      require('karma-jasmine-html-reporter'),
      require('karma-coverage-istanbul-reporter'),
      require('@angular-devkit/build-angular/plugins/karma')
    ],
    client: {
      clearContext: false // leave Jasmine Spec Runner output visible in browser
    },
    coverageIstanbulReporter: {
      dir: require('path').join(__dirname, './coverage/your-project-name'),
      reports: ['html', 'lcovonly', 'text-summary'],
      fixWebpackSourcePaths: true
    },
    reporters: ['progress', 'kjhtml', 'coverage-istanbul'],
    port: 9876,
    colors: true,
    logLevel: config.LOG_INFO,
    autoWatch: true,
    browsers: ['EdgeHeadless'],
    singleRun: true,
    restartOnFileChange: true,
    customLaunchers: {
      EdgeHeadless: {
        base: 'Edge',
        flags: ['--headless']
      }
    }
  });
};

When I run: npx karma start --single-run --browsers EdgeHeadless

I get those logs
