How to use the react-app-rewired/scripts/utils/paths.appIndexJs function in react-app-rewired

module.exports = function override(config, env) {
  config = injectBabelPlugin(
    ["import", { libraryName: "antd", style: true, libraryDirectory: "es" }],
    config,
  );

  if (env === "production") {
    // Remove default polyfills
    config.entry = { main: paths.appIndexJs };

    // Change css module class names in production
    const cssLoader = getLoader(
      config.module.rules,
      rule => String(rule.test) === String(/\.module\.css$/),
    ).loader.find(loader => loaderNameMatches(loader, "css-loader"));
    cssLoader.options.localIdentName = "ma-[hash:base64:8]";

    // Include bundle analyzation
    config.plugins.push(
      new BundleAnalyzerPlugin({
        analyzerMode: "static",
        openAnalyzer: false,
      }),
    );
  }
