Select as a defaut value the first item of a "sharepoint data component"

Hi there,

I’m working on a POC using team Forms.

I try to get a single value of a sharepoint list by addind a filter options on a « sharepoint Data Component » :

My items list is filtered and I’m quite happy. But in fact, I want to select the first value of the list as a default value…

I try to modify the « calculated value »  as below :

So my question : How can I calculate in a  TEXT FIELD or select the first item of a filtered sharepoint data component ?

Thank you for support !
