Start a chat session and send a manually defined message to the Visitor.
Note: In most cases, using .startLink() is preferable. In some very specific use cases, .openProactiveChat() would work as well.
- String | (Required)
- A string containing the first chat message to be sent to the Visitor when this function fires.
Example: SnapEngage.startChat(“Hey there, what can I do for you?”)
