PHP Google Api Client SQL Admin not enable Auth IP - php

Question

I have this code that updates my Google MySQL instance authorized IPs, connection is ok, the code prints me the current IP's but it cannot add a new IP to the settings I tried many ways but it still do not works it doesn't make any change to the Instance configuration.
$client = new Google_Client();
$client->setAuthConfig('../config/service-account.json');
$client->setApplicationName(env("APP_NAME"));
$projectName = env("GOOGLE_PROJECT_NAME");
$instanceName = env("SQL_INSTANCE_NAME");
$scopes = [
"https://www.googleapis.com/auth/sqlservice.admin",
"https://www.googleapis.com/auth/compute",
];
$client->addScope($scopes);
$sql = new Google_Service_SQLAdmin($client);
$sqlAdmin = new Google_Service_SQLAdmin_Settings($client);
$instanceSettings = $sql->instances->get($projectName, $instanceName)->getSettings();
$authNetworks = $instanceSettings->getIpConfiguration();
$newAuthNetwork = new Google_Service_SQLAdmin_AclEntry($client);
$newAuthNetwork->setName("tmp_ip_connection");
$newAuthNetwork->setKind("sql#aclEntry");
$authNetworks->setAuthorizedNetworks($newAuthNetwork);
$ipv4 = file_get_contents('https://api.ipify.org');
$newAuthNetwork->setValue($ipv4);
$ipConfiguration = new Google_Service_SQLAdmin_IpConfiguration($client);
$ipConfiguration->setIpv4Enabled(true);
$ipConfiguration->setAuthorizedNetworks([$newAuthNetwork]);
$instanceSettings->setIpConfiguration($ipConfiguration);
$sql->instances->get($projectName, $instanceName)->setSettings($instanceSettings);
//TODO why it is not working??
print_r($sql->instances->get($projectName, $instanceName)->getSettings()->getIpConfiguration()->getAuthorizedNetworks());

The main thing missing from yours is you never updated the instance after you made the change.
Working example:
$client = new Google_Client();
$client->setAuthConfig('../config/service-account.json');
$client->setApplicationName(env("APP_NAME"));
$projectName = env("GOOGLE_PROJECT_NAME");
$instanceName = env("SQL_INSTANCE_NAME");
$scopes = [
"https://www.googleapis.com/auth/sqlservice.admin",
"https://www.googleapis.com/auth/compute",
];
$client->addScope($scopes);
$sql = new Google_Service_SQLAdmin($client);
$instances = $sql->instances;
$instance = $instances->get('projectId', 'instanceId');
$networks = $instance->getSettings()->getIpConfiguration()->getAuthorizedNetworks();
$values = [];
foreach ($networks as $network) {
$values[$network->getName()] = $network;
}
$values['1.production'] = array_get($values, '1.production', clone head($values));
$external_ip = #file_get_contents('http://ipecho.net/plain');
$values['1.production']->setValue("$external_ip/32");
$values['1.production']->setName('1.production');
$instance->getSettings()->getIpConfiguration()->setAuthorizedNetworks(array_values($values));
$instances->update('projectId', 'instanceId', $instance);
