This workflow accounts for this behaviour.\n### What it Does\nThis workflow allows users to send several messages in quick succession, treating them as one coherent conversation instead of separate messages requiring individual responses. \n### How it Works\n1. When messages arrive, they are stored in a **Supabase PostgreSQL** table\n2. The system waits briefly to see if additional messages arrive\n3. If no new messages arrive within the waiting period, all queued messages are:\n - Combined and processed as a single conversation\n - Responded to with one unified reply\n - Deleted from the queue"
