AfterBackendUserListConstraintsAssembledFromDemandEvent

New in version 14.0

The PSR-14 event \TYPO3\CMS\Backend\Controller\Event\AfterBackendUserListConstraintsAssembledFromDemandEvent is dispatched when the backend user repository fetches a list of filtered backend users (itself called when displaying the list of users in the backend module). It makes it possible to modify query constraints based on currently active filtering.
