How to apply transforms to a Bundle like we used to do in Asp.Net MVC 4? about bundling HOT 2 CLOSED

        app.UseBundling(bundles =>
        {
            // building an advanced configuration in code
            //bundles.AddCss("/virtual-path/to/bundle.css")
              //  .Include("/physical-path/to/include.css")
                //.Include("/another/physical-path/to/pattern*.css")
                //.Exclude("/**/*.min.css");

            //bundles.AddLess("/virtual-path/to/less-bundle.css")
              //  .Include("/physical-path/to/main.less");
            
            foreach (var culture in SupportedCultures)
            {
                bundles.AddJs($"/js/modules/myModulesBundle.{culture.Name}.js")
                    .Include("/js/module1.js")
                    .Include("/js/module2.js")
                    // this is THE KEY STEP: insert the translator in the bundle item transformation pipeline
                    .UseItemTransforms(transforms => transforms.Insert(0, new JSTranslator()));
            }
        });

public class JSTranslator : BundleItemTransform
    {
        public override void Transform(IBundleItemTransformContext context)
        {
            string translated = TH.STranslator(context.Content);  // TH is some Helper class to do the exact translation
            context.Content = translated;
        }
    }
