Facebook Messenger Bot

I am trying to set up a simple scenario where a facebook user messages a page and receives an answer.

I have followed this tech article to a tee, but I cant get the scenario to recognize the message.

I have the bot built and connected in my facebook developer account to make. I have created a separate developer test account to trigger the action, but I cant figure out why Make doesn’t recognize it when it happens.

The only thing I havent completed is some of the additional details Facebook needs about the app. But it asks for a demo, which I cant do until its connected haha. Photo for reference.
