Query binding transform: extract data from dataset

Hello
i'm stuck in searching and cannot find a post. Perhaps just wrong searching
I have a named query which is giving following result:

[{"substring":"2024-02-09","payern1":"User Info"}]

I need to use 2024-02-09 in a label and User Info in another. I know there is a fast solution but I'm not able to find it.

Thanks to everybody
