Create Gmail Replies or Drafts with ChatGPT Automatically: GAS105

Introduction

In this Google Apps Script project, I am using ChatGPT to generate a reply message by providing the messages in the Gmail thread. The reply can be then sent out directly or created as a draft so you can review before sending it out, you can add multiple rules in the Google Sheets to handle different situations with different prompts to ChatGPT.
