LinkedIn Lead Generation: Auto DM System with Comment Triggers using Unipile & NocoDB

• Connection Status Check: Determines if users are 1st-degree connections
• Automated DMs: Sends personalized messages with lead magnet links to connected users
• Connection Requests: Asks non-connected users to connect via comment replies
