Как опубликовать событие непосредственно в календаре другого пользователя

Я хочу опубликовать событие непосредственно в календаре другого пользователя с помощью jamesiarmes / php-ews, но в примере я нашел только то, как сделать это с приглашением.

У меня есть учетная запись администратора, поэтому я могу писать в личном календаре пользователя athers напрямую.

Я не очень понимаю, потому что я новичок в EWS, так что спасибо за любую помощь.

// Replace this with your desired start/end times and guests.

$attendee->Mailbox->EmailAddress = $guest['email'];
$attendee->Mailbox->Name = $guest['name'];

}
// Add the event to the request. You could add multiple events to create more
// than one in a single request.
$request->Items->CalendarItem[] = $event;
$response = $client->CreateItem($request);
// Iterate over the results, printing any error messages or event ids.
$response_messages = $response->ResponseMessages->CreateItemResponseMessage;
foreach ($response_messages as $response_message) {
