Using Panel Library


I have tried to use Panel library as showed in the chatbot video in the google cloud workbench.
When running the following cell:

Only send message box with related buttons appears, but adding a text there (e.g hi) there, nothing happens. Basically it is not interactive.

I also tried it on Google Colab, there after sending ‘hi’ in the text box, it prints the Hi, but no response from LLM showed up.

I am wondering what are the requirements for Panel to work properly?
