Is there any provision in Frappe to enforce role-based file access? Consider two Attach fields: one named dont_secure and another named secure. Role_1 has access only to the dont_secure field, while Role_2 has access to both dont_secure and secure. This setup works correctly when permission levels are configured properly. However, the issue is that if a user with Role_1 knows the file name, they can still access it directly using the
URL: http://my.com/private/files/filename.
How can this be prevented? My Frappe Version is 15
