How to present a controller by giving some margin from Y axis?

[mohsinbmwm3]

Hello,

I am trying to present a UIViewController with Presentr controller.

let width = ModalSize.custom(size: Float.init(scheduleDispPrefVC.preferredContentSize.width))
        let height = ModalSize.custom(size: Float.init(scheduleDispPrefVC.preferredContentSize.height))
        let center = ModalCenterPosition.customOrigin(origin: CGPoint(x: 0, y: 100))
        let customType = PresentationType.custom(width: width, height: height, center: center)
        
        presenter = Presentr.init(presentationType: customType)
        presenter?.backgroundOpacity = 0.25
        presenter?.transitionType = TransitionType.coverVerticalFromTop
        presenter?.dismissTransitionType = TransitionType.coverVerticalFromTop
        presenter?.backgroundTap = BackgroundTapAction.passthrough
        customPresentViewController(presenter!, viewController: scheduleDispPrefVC, animated: true)

ScheduleViewOption is the new vc which i am trying to present below app header but when it is presented then i am not able to click header buttons.
When I run this I get as shown in image.
