auth_property_name envar

Should there be a envar in template.env for auth_property_name in Azure AD (Entra) authentication section?

It is coded in app/Plugin/AadAuth/Controller/Component/Auth/AadAuthenticateAuthenticate.php

self::$auth_property_name =  Configure::read('AadAuth.auth_property_name') ?? 'userPrincipalName';

        public function __construct()
        {
                self::$client_id = Configure::read('AadAuth.client_id');
                self::$ad_tenant =  Configure::read('AadAuth.ad_tenant');
                self::$client_secret =  Configure::read('AadAuth.client_secret');
                self::$redirect_uri =  Configure::read('AadAuth.redirect_uri');
                self::$auth_provider =  Configure::read('AadAuth.auth_provider');
                self::$auth_provider_user =  Configure::read('AadAuth.auth_provider_user');
                self::$misp_user =  Configure::read('AadAuth.misp_user');
                self::$misp_orgadmin =  Configure::read('AadAuth.misp_orgadmin');
                self::$misp_siteadmin =  Configure::read('AadAuth.misp_siteadmin');
                self::$check_ad_groups =  Configure::read('AadAuth.check_ad_groups');
                self::$auth_property_name =  Configure::read('AadAuth.auth_property_name') ?? 'userPrincipalName';

                $this->Log = ClassRegistry::init('Log');
                $this->Log->create();

                $this->settings['fields'] = ['username' => 'email'];
        }
