Follow the steps in our articles "How to Add a Chat Widget to Funnels and Websites" and "How to Add a Chat Widget to a Wordpress Site" to learn how to customize a chat widget.
After the widget is setup, you'll need to create a trigger to send a notification that a conversation's been initiated in the widget.
Step 1: Navigate to Triggers > + Add Trigger. Set up the trigger as shown below:
Step 2: The trigger event should be "Customer Replied" and the filter for "Reply Channel" = "Chat Widget" should be enabled.
Step 3: For the trigger actions, use the "Message Body" custom value in a notification SMS or email. (The screenshot included uses a SMS for this example.) This custom value will display the chat widget message in the notification.
Step 4: Save and activate your trigger.
