How to prompt user to access chat bot in webchat as seen in rasa demo bot?

Hello, I have a similar question to this topic related to the tooltipPayload. In my current configuration, I have something like this:

WebChat.default.init({
        selector: "#webchat",
        initPayload: "/welcome",
        socketUrl: "http://localhost:5005",
        socketPath: "/socket.io/",
        title: "Testbot",
        tooltipPayload: "/Popup",
        subtitle: "",
    })

The issue is that only the tooltipPayload is sent taken into account by the bot. Ideally, I would like the bot to show the tooltip when the webchat is closed, and once a user opens it the initPayload is sent to the bot.

Is there something I’m missing?
