Add user authentication to offline related modules

we need to add user authentication to offline related modules after #3678 merged

The issue references adding user authentication to offline related modules after a previous PR #3678. First, examine the changes from PR #3678 to understand the current offline module structure. Then, locate the offline modules in the codebase, likely under directories like 'src/offline' or 'src/engine'. Determine what authentication mechanism is required (e.g., integrating with existing auth systems) and identify entry points for adding auth checks. 'Done' means authentication is implemented and tested for offline operations.
