Extract processed CSS as property on VueJS component for run time

Is it possible to get the css for a vue js component and attach it as a string to a component when building a library for use at run time?

vue-cli-service build --mode production --target lib --name components src/index.ts

I currently achieve this for some custom js using a custom block

vue.config

...
 rules: [
      {
        resourceQuery: /blockType=client-script/,
        use: './client-script-block',
      },
   ],
},
...

client-script-block.js

module.exports = async function () {

  return `export default function (Component) {
      Component.options.__client_script = ${JSON.stringify(this.resourcePath)};
    }`;
};

Which then exposed the string in the vue app that uses the library.

But achieving the same thing with CSS doesnt seem to play ball.

any ideas?
