Why this helps
Finding a temporary source again can take longer than the conversion task itself.
- Retrieve the original uploaded file by its ID.
- Skip a manual search through temporary file handling steps.
- Keep the retrieval request in a direct conversation.

- 2Create an automation in the portal or ask Notis to retrieve an uploaded file when its ID is sent by DM.
- 3State in one plain-language instruction that Notis should use the supplied file ID and report the result.
- 4Choose Direct Message Received as the trigger and choose a channel for run reports.
- 5Test with a valid uploaded file ID before it expires.
