$options do not override JWT in getAccessToken

[tayeke]

The method getAccessToken (https://github.com/patrickbussmann/oauth2-apple/blob/main/src/Provider/Apple.php#L236) does not use the $options override when creating the JWT token. The practical example for this is that I need to set a specific client_id for the request. The result now is that I have a client_id in the request payload that matches, but the sub (client_id) in the payload of the client_secret JWT doesn't match.

public function getAccessToken($grant, array $options = [])
{
    $configuration = $this->getConfiguration();
    $time = new \DateTimeImmutable();
    $time = $time->setTime($time->format('H'), $time->format('i'), $time->format('s'));
    $expiresAt = $time->modify('+1 Hour');
    $expiresAt = $expiresAt->setTime($expiresAt->format('H'), $expiresAt->format('i'), $expiresAt->format('s'));

    $token = $configuration->builder()
        ->issuedBy($this->teamId)
        ->permittedFor('https://appleid.apple.com')
        ->issuedAt($time)
        ->expiresAt($expiresAt)
        ->relatedTo($this->clientId) // THIS LINE SHOULD USE CLIENT_ID FROM $OPTIONS IF PRESENT
        ->withHeader('alg', 'ES256')
        ->withHeader('kid', $this->keyFileId)
        ->getToken($configuration->signer(), $configuration->signingKey());

    $options += [
        'client_secret' => $token->toString()
    ];

    return parent::getAccessToken($grant, $options);
}
