getting to user defined position other than 0

Hello, I am trying to implement this library. The list view is displayed in the android activity when the item in list view is clicked it displays the content related to the clicked list element inside the foldable layout.
For that during i have to get to the list view clicked item's content and not to the first content.

how to make the foldable layout to directly show the 10 or 24th element.
Note scrolltoposition is not fit for me to use
