Remove unused css on one page.

Hello guys im trying to get the csspurify plugin to work with laravel mix and im trying to remove the unused css on one file only. So far is not working.

const { mix } = require('laravel-mix');

mix.webpackConfig({
    resolve: {
        plugins: [

            new PurifyCSSPlugin({
                // Give paths to parse for rules. These should be absolute!
                paths: glob.sync(path.join(__dirname, 'resources/views/index.blade.php')),
            })
        ]
    }
});


mix.styles([
    'public/assets/css/style.css',
    'public/assets/vendor/font-awesome/css/font-awesome.min.css',
    'public/assets/vendor/owlcarousel/assets/owl.carousel.min.css',
    'public/assets/vendor/owlcarousel/assets/owl.theme.default.min.css',
    'public/assets/css/vendor/settings.css',
    'public/assets/css/vendor/prettyPhoto.css',
], 'public/css/all2.css');
