Is it possible to make feature layers in a public StoryMap not accessible to others in ArcGIS Online/Pro? I have the box checked in the layer settings to not allow the layers to be exported, but users can still find them in the content search and run basic analysis on it as a virtual layer. If I make the feature layers private to my organization, users are prompted to sign in when viewing the StoryMap or web map even though those are both set to public.
