The default chat button connects your customers to the chat window so
they can start a chat from your web page. Valid values are true and
false.
The legacy chat product is in maintenance-only mode, and we
won't continue to build new features. You can continue to use it, but we no longer
recommend that you implement new chat channels. Instead, you can modernize your
customer communication with Messaging for In-App and Web. Messaging
offers many of the chat features that you love plus
asynchronous conversations that can be picked back up at any time.
