Access token vimeo and how to get exactly my feeds?

Question

PHP

For information, I create a link that the user clicks on to get a token

require("classes/vimeo/autoload.php");
$client_id = '';
$client_secret = '';
echo "This is an unauthenticated request to /users/dashron<br />";
$lib =  new \Vimeo\Vimeo($client_id, $client_secret);
$_SESSION['state'] = base64_encode(openssl_random_pseudo_bytes(30));
echo 'To authenticate you should click <a href="'
    . $lib->buildAuthorizationEndpoint('url', 'public', $_SESSION['state'])
    . '">here</a><br />';

When processing a transition

require("classes/vimeo/autoload.php");
$client_id = '';
$client_secret = '';
$token = '';
$lib =  new \Vimeo\Vimeo($client_id, $client_secret);

$tokens = $lib->accessToken($_GET['code'], 'url');
if ($tokens['status'] == 200) {
    echo $_SESSION['access_token'] = $tokens['body']['access_token'];

}
$lib->setToken($_SESSION['access_token']);
    $response = $lib->request('/me/feed', array('per_page' => 20,'page'=>1), 'GET');
var_dump($response['body']);

How to save this token, it just turns out that in order to get $_GET['code'] you need to confirm the transition every time, and I need to put a check on cron. How can I generate code, maybe I chose the wrong approach?
Well, the question is, who knows, left advertising videos will fall out, how can they be removed from the feed, otherwise they are parsed along with the necessary information
