Adding Facebook Messenger chat window

Add Facebook Messenger chat to your website for easier communication with your customers.
First of all, generate the chat window code on Facebook according to the official instructions.

Once you have successfully generated the code, log in to your Voog account and navigate to Settings > Site. Add the copied code to the External tracking code field. If you already have some previous code snippets there, then leave an empty line between those. After you have added your code, scroll down and press the green Save settings button.
