The community member who posted the original question asked if there is a way to assign a chat store to an agent after initializing the agent, using the example agent.chat_store = redis_chat_store. In the comments, another community member responded that this may not be possible after initializing the agent. The recommended approach is to manage the chat store/memory outside of the agent and pass in the chat history when calling the agent's chat method, like agent.chat("msg", chat_history=chat_history). There is no explicitly marked answer in the provided information.
Your best bet is managing the chat store/memory outside of the agent, and passing in the chat history like agent.chat("msg", chat_history=chat_history)
