Thank you for looking into it!
I am not sure I understand. The widget does not support adding/showing multiple pages within the widget? I will have to go around it by adding a widget for every page I would like to show? (Adding a widget for every page works fine with the Page Builder, but is not what I am looking for)
When I add the widget via the Page Builder on a page I am actually able to add multiple pages within the widget. Screenshot of how the widget lets me select multiple pages
When I add the widget to a sidebar area via Widgets in admin, I am only able to add one page (as shown in the screenshot you added).
I want to use the widget via the Page Builder and want the widget to show all the pages I select.
I have searched for a plugin/widget which can pull multiple pages, but the ones I have found all show only one page. Is there a reason for this that I do not understand?
