Why do I can't get the list of topics

[KamenRiderKuuga]

How can I get the list of topics?

I have sent a message to pulsar with the topic: persistent://my-tenant/my-namespace/thing/properties/XnvgzQUmoctnmddfId0LY5RWX

Now, I'm sure that I can consume from the topic, but when I use the Admin API /admin/v2/:schema/:tenant/:namespace to get the topic list, I've got an empty list

I want to know which step of my operation is wrong and why this happens. Thank you!
