How to get another column values from MySQL Query in opencart3 admin panel?

Question

The code below uses 2 tables "category_path" and "category_description" to get id=>name of all categories and sub-categories. Im bad at mySql, so I would appreciate if you help me. In this function I need to also get values of 'cat_name' column FROM THE OTHER (third) table named 'category'

public function getCategories($data = array()) {
    $sql = "SELECT cp.category_id AS category_id, 
                GROUP_CONCAT(cd1.name ORDER BY cp.level SEPARATOR '  >  ') AS name, 
                c1.parent_id, c1.sort_order 
            FROM " . DB_PREFIX . "category_path cp 
                LEFT JOIN " . DB_PREFIX . "category c1 ON (cp.category_id = c1.category_id) 
                LEFT JOIN " . DB_PREFIX . "category c2 ON (cp.path_id = c2.category_id) 
                LEFT JOIN " . DB_PREFIX . "category_description cd1 ON (cp.path_id = cd1.category_id) 
                LEFT JOIN " . DB_PREFIX . "category_description cd2 ON (cp.category_id = cd2.category_id)  
            WHERE cd1.language_id = '" . (int)$this->config->get('config_language_id') . "' 
            AND cd2.language_id = '" . (int)$this->config->get('config_language_id') . "'";

You are already using that category table in the first join and you gave it an alias of c1 so

SELECT cp.category_id AS category_id, c1.cat_name,
. . .
