Question regarding creating a custom query

Hi peeps,
I’m trying to generate a custom query in the following fashion below (sidenote: I’m using Oxygen builder and I would like to integrate popular posts into their repeater element)

and of course (PHP noobie), my code below doesn’t seem to work and I would appreciate if someone can point me in the right direction to make this work.

function popular_posts_query( $query ) {
  global $post;
  if ( $query->query['post_type'][0] == 'post' ) {
    $popular_posts = array(
        'post_type' => 'post',

        'meta_key' => 'views_weekly',
        'orderby' => 'meta_value_num',
        'order' => 'DESC',

        'posts_per_page' => '3',
	);

    $query->set( 'meta_query', $popular_posts );
    $query->set( 'orderby', 'views' );
    $query->set( 'no_found_rows', true ); 
  }
}
add_action( 'pre_get_posts', 'popular_posts_query' );

?>
