Hello, This is an awesome post. I tried it but stuck in the Ngrok part. The Ngrok base URL is not running in Postman. getting 403 - forbidden error. Can we run the Base URL of Ngrok in POSTMAN? In the APEX part, I configured it and then created a button to invoke the Chatbox. Invoking is working fine but when we enter a Prompt then it gives this error "Generative Al Service with given ID or static ID not found."
