Hi Daniel,
Once you set up all the pages that you would like to include in the menu, head over to Appearance -> Menus from your WordPress dashboard. From there, you can add the pages to navigation menu. Changes made there should automatically reflect in the footer widget unless it’s a “Custom Menu” widget, in which case you can head over to Appearance -> Widgets and edit it from there.
Hope it helps.
Best Regards,
