Installation worked fine. If I klick on the link to claim ownership I get following error:

The website encountered an unexpected error. Please try again later.
Recoverable fatal error: Argument 1 passed to Drupal\workbench_moderation\ModerationInformation::isModeratableEntity() must implement interface Drupal\Core\Entity\EntityInterface, string given, called in xxx/xxx.xxx.at/modules/workbench_moderation/src/Plugin/Menu/EditTab.php on line 81 and defined in Drupal\workbench_moderation\ModerationInformation->isModeratableEntity() (line 54 of modules/workbench_moderation/src/ModerationInformation.php).

Maybe the route uses a generic placeholder rather than {node}? That's where I've seen this error happen before.
