Required. The unique identifier of the context. Format: projects/<Project ID>/agent/sessions/<Session ID>/contexts/<Context ID>, or projects/<Project ID>/agent/environments/<Environment ID>/users/<User
ID>/sessions/<Session ID>/contexts/<Context ID>.
The Context ID is always converted to lowercase, may only contain characters in a-zA-Z0-9_-% and may be at most 250 bytes long.
If Environment ID is not specified, we assume default 'draft' environment. If User ID is not specified, we assume default '-' user.
The following context names are reserved for internal use by Dialogflow. You should not use these contexts or create contexts with these names:
