I was used add_filter(‘woocommerce_shop_order_search_fields’) but it’s not working

This is my code:
`function custom_order_query_args($query_args) {
$user_id = get_current_user_id();
$workspace_id = get_current_workspace($user_id); // Ensure this returns the correct ID

if (!empty($workspace_id)) {
    $meta_query = isset($query_args['meta_query']) ? $query_args['meta_query'] : array();
    $meta_query[] = array(
        'key' => 'workspace_id',
        'value' => $workspace_id,
        'compare' => '='
    );
    $query_args['meta_query'] = $meta_query;
}

return $query_args;

}
add_action(‘woocommerce_shop_order_search_fields’, ‘custom_order_query_args’);`
