How to use the @expo/webpack-config/env.getModuleFileExtensions function in @expo/webpack-config

config.plugins.splice(plugin.index, 1, new HtmlWebpackPlugin(options));
    config.plugins.splice(
      plugin.index + 1,
      0,
      // Add variables to the `index.html`
      // @ts-ignore
      ExpoInterpolateHtmlPlugin.fromEnv(env, HtmlWebpackPlugin)
    );
  }

  // Add support for expo-constants
  // @ts-ignore: webpack version mismatch
  config.plugins.push(ExpoDefinePlugin.fromEnv(env));

  // Support platform extensions
  config.resolve.extensions = getModuleFileExtensions('electron', 'web');
  config.resolve.extensions.push('.node');

  if (!options.skipEntry) {
    if (!env.locations.appMain) {
      throw new Error(
        `The entry point for your project couldn't be found. Please install \`expo\`, or define it in the package.json main field`
      );
    }

    const electronWebpackDefaultEntryPoints = [
      path.resolve(env.projectRoot, 'index'),
      path.resolve(env.projectRoot, 'app'),
    ];
    const expoEntry = config.entry;
    config.entry = async () => {
      const entries = await resolveEntryAsync(expoEntry);

const resolvableExtensions = () => getModuleFileExtensions('web')
