tell chatgpt to output the response in Markdown format. Then drag and highlight all the text (don’t use the copy button on button). Put the ChatGPT window right next to the Docs windows on your screen. Now with the text highlighted, just left click hold and DRAG the text from ChatGPT to Docs. I have no idea why they made it this difficult!
