+When creating a DLQ topic, there is no subscription by default, so if you
don't subscribe to this topic in time, you may lose some messages in the DLQ.
You can specify the `initSubscriptionName` to make it automatically create the
initial subscription on the DLQ.
Review comment:
```suggestion
By default, there is no subscription during a DLQ topic creation. Without a
just-in-time subscription to the DLQ topic, you may lose messages. To
automatically create the initial subscription for the DLQ, you can specify the
initSubscriptionName parameter.
