My nodejs app calls `nexmo` API to send SMS message. Here is the API:

```
nexmo.message.sendSms(sender, recipient, message, options, callback);

```

In the app, it is

```
const nexmo = new Nexmo({
                apiKey: "nexmoApiKey",
                apiSecret: "nexmoSecret"
            }, { debug: true });        

nexmo.message.sendSms(nexmo_sender_number, cell_country + to, message, {type: 'unicode'}, async (err, result) => {....});

```

Is there a way I can convert it to async/await structure like below:

```
const {err, result} = nexmo.message.sendSms(nexmo_sender_number, cell_country + to, vcode, {type: 'unicode'});
if (err) {.....};
//then process result...

```

I would like to return the `message` to parent function after the message was successfully sent out.
