webpack not honoring swiper modules: how to?

Hi, I'm doing some tests, my index.js is just this:

import Swiper, { Navigation, Pagination } from 'swiper';
console.log(Swiper);

And this is my webpack config:

const path = require('path');
const BundleAnalyzerPlugin = require('webpack-bundle-analyzer').BundleAnalyzerPlugin;

module.exports = {
  //mode: 'development',
  mode: 'production',
  watch: true,
  entry: {
    index: './src/index.js',

  },

  output: {
    filename: '[name].js',
    path: path.resolve(__dirname, 'dist'),
    clean: true,
  },


  plugins: [
    new BundleAnalyzerPlugin()
  ],

  module: {
    rules: [
      {
        test: /\.m?js$/,
        exclude: /node_modules/,
        use: {
          loader: "babel-loader",
          options: { presets: ['@babel/preset-env'] }
        }
      } // babel
    ] // rules
  } // module
};

Well, the BundleAnalyzer graph shows that ALL the swiper modules are bundled. Why? How can I avoid that?

I think this question is better to address to webpack
