How to handle exceptions (429 to many requests)

[GDmac]

Does anybody have an example how to handle 429 Too Many Requests responses here?
Spatie Client determineException is only for 400 and 409 errors creating a BadRequest exception
(with a public property $response)

https://github.com/spatie/dropbox-api/blob/master/src/Client.php#L664-L671

For other errors it just passes thru the guzzle ClientException
(which uses method getResponse())

The idea is that the dropbox response-headers contain a retry-after header
to determine the timeout before retry.

 try { 
     // ... move / upload
 } catch (\Spatie\Dropbox\Exceptions\BadRequest $e) {
     $errorResponse = $e->response;
 } catch (\GuzzleHttp\Exception\ClientException $e) {
     $errorResponse = $e->getResponse();
 } finally {
     if ($errorResponse ?? null) {
         // ...
     }
 }
