Widgets missing when using child theme

Following the page here: https://docs.oceanwp.org/article/505-import-the-parent-theme-customizer-settings-into-your-child-theme

This works fine for most Customiser settings, however all widgets are missing and not retained from the main theme.

The page above does not reference anything about widgets not being able to import, are these expected to be re-created manually?
