I am trying to serve the application behind Ngrok using Docker Compose. I map port 5173 to 3000, and I see this in the terminal:

chat_app | VITE v5.4.6 ready in 2715 ms
chat_app |
chat_app | ➜ Local: http://localhost:5173/
chat_app | ➜ Network: http://192.168.97.3:5173/

However, when I open this URL, the “backend required” warning appears. How can I resolve this?
