In AbstractIdentityCacheService, there is an abstract method to return the CronExpression. There is also an inherited method to return the CronTrigger, which itself in most subclasses relies on the underlying CronExpression. This overlap of responsibilities resulted in a bug in https://github.com/camunda/camunda-optimize/pull/4107. We should refactor this class to remove this overlap of responsibilities between both methods. We might even be able to remove the method to get the trigger entirely
