propTypes not informing description

Describe the bug Probably not a bug, but I can’t figure out docspage esp in regards to slot proptypes informing description and

To Reproduce

/**
 * some cool docs
 */

export const Button = (props) => {
  return <Cb {...props} />
}
Button.propTypes = {
  actionType: PropTypes.oneOf(['positive', 'negative', 'neutral', 'error', 'warning']),
};

Expected behavior Something like this

Took me a bit, but I did eventually figure out how to get react-docgen running on the project by adding it to our custom babelrc file.

For what it’s worth, I’m seeing more or less the same issue with my component and I’m definitely not using CRA, so unsure if that bug would affect my use-case.

This is what I end up with:

const Button = (props) => {
// Component stuff here.
};

Button.propTypes = {
  /**
   * Whether or not to center the button.
   */
  centerAlign: PropTypes.bool,
  /**
   * The color theme to apply to the button.
   */
  color: PropTypes.oneOf([...buttonColors, ...brandColors]),
  /**
   * Classes to apply to the column element to adjust it's responsive width.
   */
  columnClasses: PropTypes.string,
  /**
   * The classes to apply to the outer grid element.
   */
  gridClass: PropTypes.string,
  /**
   * The text the button should display.
   */
  text: PropTypes.string,
  /**
   * The URL the button should link to.
   */
  url: PropTypes.string,
  /**
   * Whether or not the button's link should open in a new tab.
   */
  urlOpenNewTab: PropTypes.bool,
  /**
   * The button variant to use.
   */
  variant: PropTypes.oneOf(variants),
};

Button.defaultProps = {
  centerAlign: true,
  color: 'upgrade',
  columnClasses: '',
  gridClass: '',
  text: '',
  url: '',
  urlOpenNewTab: false,
  variant: 'solid',
};

I did at least get one step closer than the original author by setting Button.defaultProps to get the defaults column working, but the descriptions are a no-go both in textual description and for showing the actual types.
