Copy the below piece of sample code in the Trigger Handler:

response = Map();
response.put("action", "reply");
response.put("replies", {
    {
        "text": "Hey! Got a question? I can help."
    }
});
options = {
    "Just browsing",
    "I want to buy",
    "I need assistance"
};
response.put("suggestions", options);
return response;
