Increase Your Response Rate with Post-Chat Updates
We know that customer feedback is important to you. We also know that your customers are less likely to visit your post-chat URL if they can choose to close the chat.

Where: This change applies to Salesforce Classic and Lightning Experience in Professional, Enterprise, Unlimited, and Developer editions that use the Snap-in code snippet version 5.0 or later.
