When passing the chat history, should I be changing the 'assistant' role to 'ReqGatheringAgent' in below example?

name="ReqGatheringAgent",
system_message=self.ReqGathering_system_msg,
llm_config=self.llm_config,
chat_messages={user_proxy_agent: [{'role':'user', 'content':'What is 1+2?'}, {'role':'assistant', 'content','3'}]}
