- Updated 'start-sync' IPC event to include cookie retrieval for authentication.
- Implemented error handling for missing access tokens and Graph API responses.
- Added dynamic import for 'node-fetch' to facilitate HTTP requests.
- Cleaned and encoded OneDrive paths for API queries.
- Logged available cookies and API error details for better debugging.
