The community member who posted the original question is unsure whether they need to manually append user and assistant messages to the chat history, or if it happens automatically. The comments indicate that it depends on the specific action being used - for the "Ask assistant" action, the messages are appended automatically, but for the "Create chat completion" action, the user would need to manually add the messages to the history.
Thanks. I notice some of the templates have a block to append the user message to the chat history so I wasn't sure what needs to be manually added to the history.
