Im following the official [docs](https://ant.design/docs/react/use-with-create-react-app) but it is not working for me. I installed the less, less-loader and customize-cra and then I added `config-overrides.js` go the root directory of React app. The `config-overrides.js` looks like this:

```
import { addLessLoader, fixBabelImports, override } from 'customize-cra'

module.exports = override(
  fixBabelImports('import', {
    libraryName: 'antd',
    libraryDirectory: 'es',
    style: true
  }),
  addLessLoader({
    javascriptEnabled: true,
    modifyVars: {
      '@primary-color': '#1DA57A',
      '@link-color': '#1DA57A',
      '@success-color': '#1DA57A',
      '@warning-color': '#1DA57A',
      '@error-color': '#1DA57A'
    }
  })
)

```

The colors in the app are still default Ant Design colors. What am I missing, please? 

Thank you.
