Order notes column without “system” notes

Hi – I’m using code below to show/list order notes in a separate column in the orders overview. Can someone help me with editing this code to only show notes from registered admins and not from “system”?

Thanks!

// WooCommerce – Add order notes column to orders list
// Code goes in functions.php for your child theme
// not tested in a PHP snippet plugin

// Add column “Order Notes” on the orders page
add_filter( ‘manage_edit-shop_order_columns’, ‘add_order_notes_column’ );
function add_order_notes_column( $columns ) {
$new_columns = ( is_array( $columns ) ) ? $columns : array();
$new_columns[‘order_notes’] = ‘Hinweis’;
return $new_columns;
}

add_action( ‘admin_print_styles’, ‘add_order_notes_column_style’ );
function add_order_notes_column_style() {
$css = ‘.post-type-shop_order table.widefat.fixed { table-layout: auto; width: 100%; }’;
$css .= ‘table.wp-list-table .column-order_notes { min-width: 280px; text-align: left; }’;
$css .= ‘.column-order_notes ul { margin: 0 0 0 18px; list-style-type: disc; }’;
$css .= ‘.order_customer_note { color: #ee0000; }’; // red
$css .= ‘.order_private_note { color: #0000ee; }’; // blue
wp_add_inline_style( ‘woocommerce_admin_styles’, $css );
}

// Add order notes to the “Order Notes” column
add_action( ‘manage_shop_order_posts_custom_column’, ‘add_order_notes_content’ );
function add_order_notes_content( $column ) {
if( $column != ‘order_notes’ ) return;
global $post, $the_order;
if( empty( $the_order ) || $the_order->get_id() != $post->ID ) {
$the_order = wc_get_order( $post->ID );
}
$args = array();
$args[‘order_id’] = $the_order->get_id();
$args[‘order_by’] = ‘date_created’;
$args[‘order’] = ‘ASC’;
$notes = wc_get_order_notes( $args );
if( $notes ) {
print ‘

‘;
foreach( $notes as $note ) {
if( $note->customer_note ) {
print ‘<li class=”order_customer_note”>’;
} else {
print ‘<li class=”order_private_note”>’;
}
$date = date( ‘d/m/y H:i’, strtotime( $note->date_created ) );
print $date.’ by ‘.$note->added_by.'<br>’.$note->content.’‘;
}
print ‘

‘;
}
} // end function
