Decorator to enable users to continue a conversation. Requires both data persistence and authentication to be enabled. This decorator will automatically:
  • Send the persisted messages and elements to the UI.
  • Restore the user session.
Only JSON serializable fields of the user session will be saved and restored.

​
Usage

At minimum, you will need to use the @cl.on_chat_resume decorator to resume conversations. 
@cl.on_chat_resume
async def on_chat_resume(thread):
    pass
However, if you are using a Langchain agent for instance, you will need to reinstantiate and set it in the user session yourself.
