How to retrieve the current Query Filter Definition

Hello,

I need to be able to retrieve the active Filter Query Definition on a document from the API to be able to execute it in a client-side java function that uses the Gateway.
The gateway is able to do it natively in one so I think there must be a way.

I am able to retrieve all the information I need via the API on the document I am processing however I am looking for how to retrieve the Query Definition Filter.
I don't see any API method that can do that or even a CLI command.

Here is a simple example of a Query Filter Definition I would like to get :
(field["State"]="Active")

I'm on WRV&S 12.4.0.5

Have a nice day,
Alex
