Rasa-hq/rasa-chat widget: Adding a welcome message

Hello, I am using this widget to integrate my chatbot into my website. Does it have an option for triggering an initial welcome message? Has anyone used it? Using the REST API would not be a problem since starting the “greet” intent is relatively simple. Since it uses sockets to connect to the rasa server, I need to learn how to reverse engineer it to write some JS code that triggers the welcome message. Since there is no documentation for this widget, I’d like to ask if it might have this option.
