Location Zotero files: Cloud or WebDav a solution?

Good morning,

I have been using the integrated Sync-option between my Logseq-installation on my MacBook and my iPad since some days and I like it so far. Since I am using the integration with Zotero and the PDF-reader I am trying to figure out, with which files storage solution in Zotero I can access publications on both devices. I have tried iCloud storage and OneDrive with the Zotfile-extension but I cannot reference the right path on my iPad for the Zotero-settings on iPad.

1.) Did anybody find out if this is possible?
2.) Would a WebDav-approach (e.g. Owncloud webdav) a solution?

Thanks!

Marco
