Facebook-API: how to set "option" instead of "setting/value" when writing settings for page

TLDR i try to change a setting for one of my facebook-pages by API. The Syntax has changed but i can not figure out how.

whole story

The example code from the docs is:

/* PHP SDK v4.0.0 */
/* make the API call */
$request = new FacebookRequest(
  $session,
  'POST',
  '/{page-id}/settings',
  array (
    'setting' => 'USERS_CAN_POST_VIDEOS',
    'value' => false,
  )
);
$response = $request->execute();
$graphObject = $response->getGraphObject();
/* handle the result */

if i try that i get the following exception:

(#12) 'setting' is deprecated for versions v2.2 and higher

Which seems to be noted in the changelog here

But i can not figure out the new syntax. When i try the following:

$request = new FacebookRequest(
  $session,
  'POST',
  '/{page-id}/settings',
  array (
    'option' => array(
            'USERS_CAN_POST' => true
        )
  )
);

i get this error:

OAuthException (#100) option requires exactly one key"

And with this syntax:

$request = new FacebookRequest(
  $session,
  'POST',
  '/{page-id}/settings',
  array (
        'USERS_CAN_POST' => true
    )
);

Error this time:

(#100) Requires exactly one and only one of the params: option,setting

So which is the correct syntax to set an option now?

Thanks!
