// Create a custom action to respond with a dynamic message
const myCustomAction = async (state, event, { bot, axios }) => {
    const userMessage = event.preview;
    if (userMessage.toLowerCase().includes("hello")) {
        return { text: "Hey there! How can I assist you?" };
    } else {
        return { text: "I'm still learning. Can you rephrase?" };
    }
};
// Register the action
module.exports = myCustomAction;
