+/// CrossSigningSetupCoordinatorBridgePresenter enables to start CrossSigningSetupCoordinator from a view controller.
+/// This bridge is used while waiting for global usage of coordinator pattern.
+/// It breaks the Coordinator abstraction and it has been introduced for Objective-C compatibility (mainly for integration in legacy view controllers).
+/// Each bridge should be removed once the underlying Coordinator has been integrated by another Coordinator.
