Can't Find Webhook Block in ChatGPT Builder - Need Help!

Hey everyone,

I’m trying to set up Webhook integration with Google Apps Script in ChatGPT Builder, but here’s the problem:

For example, ChatGPT tells me this:

"Add a Webhook block:

To add a Webhook block in ChatGPT Builder, select the Webhook Block in the conversation flow and add it."

But I have no idea what that means.

I’ve looked around the interface, but I can’t find anything called Webhook Block. Am I missing something, or is it hidden somewhere?

Would really appreciate any help or clarification on how to set this up!

Thanks!
