Mac-catalyst set Window max and minimum size in objective-c

I have Mac-catalyst app. I would like to know options to set the max or minimum size of a window in objective-c.

Here is an example in swift

UIApplication.shared.connectedScenes.compactMap { $0 as? UIWindowScene }.forEach { windowScene in
    windowScene.sizeRestrictions?.minimumSize = CGSize(width: 480, height: 640)
}

Could someone help provide example in objective-c
