How do I exclude specific folders and files to be uploaded to S3 using Laravel Mix and Webpack?

I tried this solution https://laracasts.com/discuss/channels/laravel/laravel-mix-upload-files-to-s3 and https://medium.com/@avosalmon/cache-busting-using-laravel-mix-and-cloudfront-s3-eb222b569f88 but it's not doing what I want to do.

const mix = require('laravel-mix');
const S3Plugin = require('webpack-s3-plugin');
require('dotenv').config();

/*

 */

let webpackPlugins = [];

if (mix.inProduction()) {
    webpackPlugins = [
        new S3Plugin({
            include: /.*\.(css|js|ico|jpg|png)$/,
            s3Options: {
                accessKeyId: process.env.AWS_ACCESS_KEY_ID,
                secretAccessKey: process.env.AWS_SECRET_ACCESS_KEY,
                region: process.env.AWS_DEFAULT_REGION,
                // endpoint: process.env.AWS_ENDPOINT,
            },
            s3UploadOptions: {
                Bucket: process.env.AWS_BUCKET,
                CacheControl: 'public, max-age=31536000'
            },
            directory: 'public',
        })
    ];
}

mix.js('resources/js/alpine.js', 'public/js')
    .js('resources/js/choices.js', 'public/js')
    .js('resources/js/clipboard.js', 'public/js')
    .js('resources/js/notyf.js', 'public/js');

mix.postCss('resources/css/app.css', 'public/css', [
        require("tailwindcss"),
    ]);

mix.disableSuccessNotifications();

mix.webpackConfig({
    plugins: webpackPlugins
});

mix.version();

When I run this code, it uploads all contents and folders with css, js, ico, jpg and png files. However, I want to exclude specific folder regardless if it contains (css, js, ico, jpg and png) files.

Example folders inside the public directory

• avatars (needs to be excluded regardless of the file types inside)
• css
• images
• js
• index.php (excluded)
• favicon.ico
