Watch changes in home directories

Greetings.

I have Nextcloud 13 (NC) installed and running with next schema:

Data dir is on mounted ntfs partition, located on hdd of current computer. There are 2 smb shared folders: users and share. Folder “share” is mounted as external storage in NC, folder “users” is the NC data directory. All these folders are in smb access from domain users. When I copy file/folder directly into “share” dir, I can see changes in NC immediately. What I need to do to see same changes in users home directories when copy files/folders directly?

If I run occ files:scan manually, changes are applying, but I need to automate this process, because users will use their own NC home folders as mounted folders on their PCs.
