Text Schema (Copy-friendly)
What is a session? A session is a continuous period of messaging activity. When there's a gap longer than the timeout between messages, a new session begins. For example, with a 15-minute timeout, if you send messages at 10:00 AM and 10:30 AM, they belong to different sessions.
