Note: Recart establishes this connection, and their support and success teams will be your best resource for implementing the messenger opt-in to your Privy displays. 
- The Recart Success Team establishes the connection by adding Messenger widgets to your active popups.
 - The Messenger widget only shows up on your display if Recart detects an active Facebook login in the browser (to avoid driving your customers to the Facebook login page).
 - In case the Messenger widget is live, both email and Messenger are required for subscription.
