Importing the CSS file requires the package "tippy.js" in addition to "@tippyjs/react".

This line from your documentation causes a compile error:
import 'tippy.js/dist/tippy.css'; // optional

Solution is to install "tippy.js" in addition to "@tippyjs/react".

If that is on purpose, please include it in the documentation.
If not, what is the proper way to import the styles?
