Submitting a post request to Google Sheets path


I’m trying to post to google sheets like was achieved in [solved] How do I create a leaderboard with google spreadsheets and get requests? through the script they link. However I’m confused what exactly to put in the post request in gdevelop. I understand generally how the http requests work, I’m mostly just confused about how they work in conjunction with google sheets. Do I send the request to the url of the spreadsheet I am trying to write to, or the google script attached to the spreadsheet? What is the path I should be using?

Thanks for any input!
