[surendransuri]

How to use the chat history feature for AgentGroupChat. I am planning to deploy the agentgroupchat solution in my conversational chat application. How to keep conversing after the group agents have completed the task. It is setting as is_complete true. When next message is sent by user it misses the previous context. How to use the previous messages. I am planning to use cosmos db for message storage.
