Error Connecting Google Sheets and Make via Webhook

I am attempting to use the Google Sheets “Watch Changes” trigger in Make.com. The help center outlines steps to connect this module to a google sheet via a webhook and a google extension (See attached image). However, when I input my webhook URL and supporting information (Sheet Name and Range of Cells) and click “Save”, nothing happens. I have tried testing the make.com scenario to see if it is receiving data and it is not. Any help would be greatly appreciated!
