Review Comment:
I see. When using flow code, it will return `Napi::promise`, right?
```node
const consumer = await client.subscribe({
topic: 'persistent://public/default/my-topic',
subscription: 'sub1',
subscriptionType: 'Shared',
ackTimeoutMs: 10000,
listener: async (msg, msgConsumer) => {
console.log(msg.getData().toString());
msgConsumer.acknowledge(msg);
},
});
```
