+
+wppconnect
+  .create()
+  .then((client) => start(client))
+  .catch((error) => console.log(error));
+
+function start(client) {
+  client.onMessage((message) => {
+    if (message.body === 'Hello') {
+      client
+        .sendText(message.from, 'Hello, how I may help you?')
+        .then((result) => {
+          console.log('Result: ', result); //return object success
