@babel/polyfill - is deprecated. Please, use required parts of `core-js` and `regenerator-runtime/runtime` separately

Question

I am having an issue trying to 'run serve' with a React-App I am working on. I am getting a bunch of error messages but I think are mainly due to this one error -

@babel/polyfill is deprecated. Please, use required parts of 'core-js' and 'regenerator-runtime/runtime' separately.

This is a webpack.config.dev.js and webpack.config.js file

const path = require('path');
const { CleanWebpackPlugin } = require('clean-webpack-plugin');
const HtmlWebpackPlugin = require('html-webpack-plugin');

module.exports = {

  output: {

Any ideas? Thank you!
