how to pass dependent input field variable to recordSelectOptionsQuery() in filament

Question

I am trying to scope the options based on the input taken from another field. How do I pass this variable inside this recordSelctOptionQuery?

recordSelectOptionsQuery(
    fn (Builder $query) => $query->whereBelongsTo(
        Item::find('id_selected_from_a_dependent_filed')
))
