How to use the @cypress/browserify-preprocessor.defaultOptions function in @cypress/browserify-preprocessor

  // see https://github.com/cypress-io/cypress-browserify-preprocessor/issues/19

  // options.onBundle = (bundle) => {
  //   bundle.ignore('graceful-fs');
  //   bundle.ignore('@cumulus/cmrjs');
  //   // bundle.ignore('@cumulus/logger');
  // };
  // const bundle = browserify(options);
  // Run specialized file preprocessor to transpile ES6+ -> ES5
  // This fixes compatibility issues with Electron
