What is the best php option to connect to outlook imap with oAuth?

Question

What would be the best option to connect to an outlook email account with PHP? I´m not sure how to declare my credentials with oAuth, should I use my e-mail as username or the client Id key as username? Should I use client secret as password?

I've been trying the following solutions with no success:

https://github.com/javanile/php-imap2

include "inc/php-imap2/vendor/autoload.php";

// Start connection
$mailbox = "{smtp.office365.com:993/imap/ssl/novalidate-cert}";
$token = base64_encode("user=" . $email . "\1auth=Bearer " . $passw . "\1\1");
$imap = @imap2_open($mailbox, $email, $token, OP_XOAUTH2);

// List all mailboxes
if ($imap) {
    $mailboxes = imap2_getmailboxes($imap, $mailbox, '*');    
    var_dump($mailboxes);
} else {
    $error = imap2_last_error();
    echo $error;
}

Return

Can not authenticate to IMAP server: A0001 NO AUTHENTICATE failed.

https://github.com/Webklex/php-imap

include "inc/php-imap/vendor/autoload.php";

use Webklex\PHPIMAP\ClientManager;
use Webklex\PHPIMAP\Client;

$cm = new ClientManager($options = []);

$client = $cm->make([
    'host'          => "smtp.office365.com",
    'port'          => 993,
    'encryption'    => 'ssl',
    'validate_cert' => true,
    'username'      => $email,
    'password'      => $passw,
    'protocol'      => 'imap',
    'authentication' => 'oauth',
]);

//Connect to the IMAP Server
$client->connect();

Return

got failure response: NO AUTHENTICATE failed.
