Scheduled Trigger: Runs automatically based on your defined time interval (daily, weekly, etc.). 2.

Generate LinkedIn Post Content: Uses OpenAI to create a professional LinkedIn post using the Post Description and Instructions from the sheet. 4. Format & Prepare Data: Formats the generated content along with the original instruction and post description for email. 5. Send for Approval: Sends an email to a predefined user (e.g., marketing team) with a custom form for approval, including a dropdown to accept/reject and an optional field for edits. 6. (Optional) Image Fetch: Downloads an image from a URL (if provided in the sheet) for future use in post visuals.
