Run a chat query. Chat pipelines are based on the `chat` template that uses a search session to include search
history in the chat. You can then specify how many search history items (query and answer) from a given search
session you want to display in the chat. You'll need a search session ID to run the query. Use the search session
 endpoints to list or create search sessions.
