Nextcloud share api?

Hello,

Could this hookshot bridge/widget could, connected with user credential to a nextcloud account (ideally automatically thanks to SSO) , let the user browse folders and files and when clicking on a file be able to send in the room the shared link of this file?
I guess it would need to use nextcloud APIs :
https://docs.nextcloud.com/server/latest/developer_manual/client_apis/OCS/ocs-share-api.html

The issue names no repository files, tests, or entry points. Start by reviewing the linked Nextcloud OCS Share API and locating how Hookshot currently implements widgets or external-service authentication; done should mean an authenticated user can browse files and post a selected file's shared link to a Matrix room.
