In my case (component wrapped with React.memo) props documentation is not displayed automatically. I used this workaround https://github.com/storybookjs/storybook/issues/8435#issuecomment-547075209 (exporting wrapped component) and now props are displayed fine.

Unsatisfying workaround is to also export your pure component and use that for documentation purposes 😭
