Need help to finish Google Apps Script in Google Sheets (Notion API)

Need help finishing Notion x Google Sheets CRM using Google Apps Script. Uploading from Sheets to Notion works, including site ID. Need patch operations for a dedicated cell range to update corresponding Notion page (ID in Col E) when a cell value in Col x is changed to x. Should be doable using GPT and corresponding GAS knowledge. Not looking for long-term commitments, just a quick hand to help this thing going.

Can provide example with hardcoded values to update page properties to notion.
