It ensures seamless synchronization of Trello card data with a Supabase database and sends timely Telegram notifications to keep team members informed about task assignments and deadlines.

Key Features

• Trello Card Syncing: Automatically registers new Trello cards in Supabase and keeps card details (e.g., due dates, URLs) updated.
• User Management: Tracks Trello user assignments in Supabase, creating new user entries and linking them to cards as needed.
• Real-Time Notifications: Sends Telegram messages when users are added to or removed from Trello cards, using dynamic, engaging message templates.
• Due Date Reminders: Schedules daily checks to notify users via Telegram about tasks due on the current day.
