 Args:
   session: string, Required. The name of the session this query is sent to. Format: `projects//agent/sessions/`, or `projects//agent/environments//users//sessions/`. If `Environment ID` is not specified, we assume default &#x27;draft&#x27; environment (`Environment ID` might be referred to as environment name at some places). If `User ID` is not specified, we are using &quot;-&quot;. It&#x27;s up to the API caller to choose an appropriate `Session ID` and `User Id`. They can be a random number or some type of user and session identifiers (preferably hashed). The length of the `Session ID` and `User ID` must not exceed 36 characters. For more information, see the [API interactions guide](https://cloud.google.com/dialogflow/docs/api-overview). Note: Always use agent versions for production traffic. See [Versions and environments](https://cloud.google.com/dialogflow/es/docs/agents-versions). (required)
