Thanks for implementing this! I am little confused how to use it.

In some specific cases the PWA is served behind an authenticated proxy (corporate network), so the request for the manifest.json file might return 401 - Unauthorized error. The solution to this is to add the attribute crossorigin=use-credentials in the include tag. Info about it. Currently there is no setup for that in the plugin, so I added that setting. So, if you need this, you need to setup this in your vue.config.js as below

module.exports = {
  pwa: {
    manifestCrossorigin: 'use-credentials',
  },
};

And it will add the attribute to the tag in the generated index.html file

Thanks so much for taking your time to clarify. I will see if I can find a good place in the documentation, and update the info via pull request. (If its not already there).
