How to use the @ephox/agar.Log.chainsAsStep function in @ephox/agar

const cTeardown = Chain.op(() => {
    TestBed.resetTestingModule();
  });

  Pipeline.async({}, [
    Log.chainsAsStep('', 'should be pristine, untouched, and valid initially', [
      cSetup,

      }),
      cTeardown
    ]),

    Log.chainsAsStep('', 'should be pristine, untouched, and valid after writeValue', [
      cSetup,
      Chain.op((v) => {
        v.editorComponent.writeValue('New Value');
        v.fixture.detectChanges();
