Make Map Areas discoverable via user.items(), or similar
When admins need to delete accounts for staff who have left the organization, all items need to be removed from the account before it can be deleted. Map Areas (for offline Field Maps) do not show up on the ArcGIS Online website GUI in the account's Content. They also do not appear as a result if using the ArcGIS API for Python to check via user.items(). If the user did not delete their own Map Areas before they left the organization, they become difficult for admins to identify and remove, and so far I've only been able to delete them manually using the AGO Assistant web site.
I have an ArcGIS Online Notebook that I've written to identify similar hidden items in the past (like Code Attachments and SQL databases) and delete them, but Map Areas remain invisible. Please consider adding Map Areas to the results of user.items(), if possible, or some other method for admins to identify and remove these items.
