Info endpoint of Command service

I did not understand the command service endpoint functionality for info.

The description says:

Requests a document status and the list of the identifiers of the users who opened the document for editing.

But the response just returns the document key, which is already provided in the request.
I expected a list of user identifies for example.

Documentation Link for the info endpoint

Hi Uli,
The response to this request is sent to the callback handler.

Hi Carl,
thanks for your fast response and the clarification.
Can you may add this information to the documentation page?

Best regards

Yes, we will add this info to the page.
