SWIFT : how to use "Files"

I have an app the reads/write to the iPad /DOCUMENTS folder… but I can’t seem to figure out how to get those files to appear in the “FILES.APP”.

iMazing says "Documents file is not accessible…need to set “File Sharing”

well I thought I did, inthe app pList file




According to https://www.appcoda.com/files-app-integration/

already had that… thanks
