css from external libraries

How to i can connect external libs css like: `import 'awesomelib/awesomelib.css`? I do not fully understand where I should connect it, and whether it is necessary to add something to server configurations?

The issue does not name a file, test, or entry point. Start by inspecting the React starter kit's existing CSS import setup and how an external library is included, then verify whether the library's stylesheet loads without server configuration changes. Done means documenting or demonstrating the supported import path and configuration requirements.
