How to use affected_rows in CI4?

I am using a custom model that extends the built-in Model in CI4. I want to know how I can perform the function $this->db->affected_rows() after deleting a row. Most examples online demonstrate how to achieve this using a custom model, rather than extending the CI4 model. Any suggestions would be appreciated.

PHP Code:

// this
return $this->db->affected_rows();

// or this
echo $this->db->affected_rows();
