Exception occured, code: 200 with message: (#200) Permissions error - php

Question

I have a problem with FB PHP SDK.
Here is my code:
require_once("autoload.php"); // set the right path
use Facebook\FacebookSession;
use Facebook\FacebookRequest;
use Facebook\GraphObject;
use Facebook\FacebookRequestException;
$APP_ID = 'APP_ID';
$APP_SECRET = 'APPSECRET';
$TOKEN = "TOKEN";
$ID = "PAGE_ID"; // your id or facebook page id
FacebookSession::setDefaultApplication($APP_ID, $APP_SECRET);
$session = new FacebookSession($TOKEN);
$params = array(
"message" => "Xoşbəxt olmamaq haqsızlıq deyilmi özümüzə qarşı?!"
);
if ($session) {
try {
$response = (new FacebookRequest(
$session, 'POST', '/' . $ID . '/feed', $params
))->execute()->getGraphObject();
echo "Posted with id: " . $response->getProperty('id');
} catch (FacebookRequestException $e) {
echo "Exception occured, code: " . $e->getCode();
echo " with message: " . $e->getMessage();
}
}
But when i try to run this code it returns an error:
Exception occured, code: 200 with message: (#200) Permissions error
in some forums i read that may be i need to approve premissons/ but when i submited premissions to FB they answered that if i am using it only for my purpose (as app admin) premisson approval is not requred.
What can be problem?

Debug your Access Token: https://developers.facebook.com/tools/debug/
Make sure it includes the manage_pages and publish_pages permission. And make sure you are using a Page Token. More information about the different Tokens:
