Unable to get SubscriptionMessageQueues

Line 95 in 1d86ea6

messageQueues, err := mqAdmin.FetchPublishMessageQueues(ctx, topic)

I'm going to implement an example of pull_from, I found related example in examples file.
But I have a doubt, why use the FetchPublishMessageQueues method?
FetchSubscriptionMessageQueues should not be used to fetch consumer queues.

Publish and Subscribe Queues should be two different queues.

But Admin does not provide the FetchSubscriptionMessageQueues interface, I think it is necessary to provide an interface to get the consumer queue.
https://github.com/apache/rocketmq-client-go/blob/1d86ea68616504c6985586d2a9bd1d47c312246f/admin/admin.go#LL33C6-L33C6

Do we need to add FetchSubscribeMessageQueues method in Admin, or do we take other methods.

func (a *admin) FetchSubscribeMessageQueues(ctx context.Context, topic string) ([]*primitive.MessageQueue, error) {
	return a.cli.GetNameSrv().FetchSubscribeMessageQueues(utils.WrapNamespace(a.opts.Namespace, topic))
}

Looking forward to your reply, thank you.

Maybe we can add examineTopicRouteInfo just like java sdk @pzhx521
