How to use dbutil in Codeigniter 4

in Codeigniter 3, i'm using $this->load->dbutil()

In Codeigniter 4, how to use that dbutil() ?

In CodeIgniter 4 there is only one method now [b]getXMLFromResult()[/b]

Database Utilities

csv query export not working in codeigniter 4

$db = \Config\Database::connect();
$dbutil = $db->dbutil;
$query = $db->query('SELECT name FROM customer where id=1');
$delimiter = ',';
$newline = "\n";
$csv = $dbutil->csv_from_result($query, $delimiter, $newline);

show error
Call to a member function csv_from_result() on null

Because there is no such method.
