   /** @var \TYPO3\CMS\Extbase\SignalSlot\Dispatcher $signalSlotDispatcher */
   $signalSlotDispatcher = \TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance(
       \TYPO3\CMS\Extbase\SignalSlot\Dispatcher::class
   );

   $signalSlotDispatcher->connect(
       \Causal\ImageAutoresize\Controller\ConfigurationController::class,
       'processConfiguration',
       \Company\MyExt\Slots\ImageAutoresize::class,
