Is this plugin compatible with Angular projects?

I tried adding below to my extended webpack config file for my Angular project

const HtmlWebpackPlugin = require('html-webpack-plugin')
const AsyncCssPlugin = require("async-css-plugin");

module.exports = {
  plugins: [
    new HtmlWebpackPlugin(),
    new AsyncCssPlugin({ })
  ]
};

But it didn't work, nothing changed in index.html, am I missing something or is this plugin incompatible with Angular?

Thanks
