Botpress

Good evening.
Please advise 🙏
I create webchat on the site. In this form it works correctly
    <script src="https://cdn.botpress.cloud/webchat/v1/inject.js"></script>
    <script>
        window.botpressWebChat.init({
            botId: "709aa9b7-f71d-4b01-9d36-xxxxxxxxx",
            hostUrl: "https://cdn.botpress.cloud/webchat/v1",
            messagingUrl: "https://messaging.botpress.cloud",
            clientId: "709aa9b7-f71d-4b01-9d36-xxxxxx",
            botConversationDescription: "This chatbot was built surprisingly fast with Botpress."

        });
    </script>
What should I add to make a welcome message appear when a customer clicks on the webchat button before they ask the first question?
