How to use the rollup-plugin-bundleutils.babel function in rollup-plugin-bundleutils

import { version } from './alien.js/package.json';

const production = !process.env.ROLLUP_WATCH;
const project = path.basename(__dirname);

export default {
    input: 'src/Main.js',
    output: {
        file: `public/assets/${project}.js`,
        format: 'iife'
    },
    plugins: [
        resolve({ browser: true }),
        glslify(),
        eslint({ include: ['src/**', 'alien.js/**'] }),
        production && babel({ compact: false }),
        production && terser({
            output: {
                preamble: `//   _  /._  _  r${version.split('.')[1]}.${project} ${timestamp()}\n//  /_|///_'/ /`
            },
            safari10: true
        })
    ],
    watch: {
        chokidar: true,
        clearScreen: false,
        include: ['src/**', 'alien.js/**']
    }
};
