Query metadata to display the orders. Woocommerce - wordpress

Question

I am trying to display the orders using the query->set() with my customer metadata. The metadata - _admin_name is stored in the wp_postmeta, and I want the admins only can view their own orders which the admin_name same with their user name.
How how can I use query->set() with my metadata?
Here is my code:
function mypo_parse_query_useronly( $wp_query ) {
global $post;
if ( $wp_query->is_admin && strpos( $_SERVER[ 'REQUEST_URI' ], '/wp-admin/edit.php?post_type=shop_order') == true) {
add_action( 'views_edit-post', 'child_remove_some_post_views' );
global $current_user;
$userName = $current_user->user_login;
$meta_query_args = array(
array(
'key' => '_user_name',
'value' => $userName,
'compare' => '='
)
);
//trying use this code
// $query = new WP_Query( $meta_query_args );
$wp_query->set( 'author', $current_user->id );
}
}
add_filter('parse_query', 'mypo_parse_query_useronly' );
//don't display the order whish is not own by current user.
function child_remove_some_post_views( $views ) {
//header('Location: '.$newURL);
unset($views['all']);
unset($views['wc-processing']);
unset($views['wc-on-hold']);
unset($views['wc-completed']);
unset($views['pending']);
return $views;
}
Have so way to do this?
Thanks.
