Using other theme from CDN

[BartJansseune]

Hi,
Is it possible to start another theme eg 'antd' when react-jsonschema-form.js is loaded from CDN?
I don't find any reference to any theme in the source code, so I have my doubts
If it would be possible, I assume one would use:
import { Form } from "@rjsf/antd";
but this results in error:

Uncaught TypeError: Failed to resolve module specifier "@rjsf/antd". Relative references must start with either "/", "./", or "../".
Thanks for any pointers,
Bart
