How does one avoid the entire organization's content showing up in the Shared With Me section in StoryMaps? When students publish an individual StoryMap, it shows up in the account of every student & teacher in the school. I've been a part of other organizations where this doesn't happen. I know it must be an admin setting, but I can't seem to find a good tutorial to help me figure out how to understand how the Organization settings side. I'd like to use this platform more widely at my school, but I need to keep the shared content organized.
