Wix file share subscriber uploaded document privacy

Question:
When a new subscription is purchased on my site. How do I connect make it so that the subscriber can view and manage only the documents they uploaded to file share?

Product:
Wix Studio Editor, Wix File Share, Wix Member Pages, Wix CMS

What are you trying to achieve:
User privacy for uploaded documents to file share.

What have you already tried:
I’ve tried numerous ways with Wix Velo set privacy permissions. Including automating member document folder creation to try and see if a new folder can be created after a plan was purchased and be managed only by the subscriber it was created for. So that the file share UI will only have the users documents and document that I myself put into it be available to be managed by the subscriber.

Additional information:*
How do I also connect an api to access documents placed in each subscribers document database? If thats possible. This is for a website that helps its subscribers by making recipe recommendations to them using documents and photos they upload.
