Last most recent post from set categories in tagdiv composer

Hi

I am currently trying to add a custom query in the data source.php file.

One can select in the composer the different categories from which to display posts.
( I set the post limit to four and four categories, “434, 19, 21, 38, 11” ).
What I am trying to achieve is that the query gets the single last most recent post from the four categories that I set in the composer. So I get to see 4 blocks, and they should each be from a different category.

I came this far but currently it is not working. Any thoughts on how to achieve this ?

            case 'one_from_each':  
                $wp_query_args['date_query'] = array(
    												'cat' => $category->term_id,
    												'post_type' => 'post',
    												'posts_per_page' => '1',
    												'post__not_in' => $do_not_duplicate
								);
                $wp_query_args['order'] = 'DESC';
                break;
