How to list out all **hidden** indices in a cluster

I'm trying to list out all hidden indices in a cluster. I tried GET _cat/indices?expand_wildcards=hidden,open&v, but even the status of the hidden index(index.hidden=true) is open, and the request lists out all open indices.
Is there a way to list out only hidden indices?

Hi @Bruce_Liu Welcome to the community!

Perhaps I am not clear what you are looking for

What version of the stack ...

Did you simply try

GET _cat/indices/.*?v
