I know this setting in XCode

enter image description here

It works well if I have to lock my entire app in one orientation

but what if I want to lock only particular view (say camera view) into landscapeRight then what should be done?

I have tried following approach

class AppDelegate: NSObject, UIApplicationDelegate {
    
    static var orientationLock = UIInterfaceOrientationMask.portrait {
        didSet {
            if #available(iOS 16.0, *) {
                UIApplication.shared.connectedScenes.forEach { scene in
                    if let windowScene = scene as? UIWindowScene {
                        windowScene.requestGeometryUpdate(.iOS(interfaceOrientations: orientationLock))
                    }
                }
            } else {
                if orientationLock == .landscapeRight {
                    UIDevice.current.setValue(UIInterfaceOrientation.landscapeRight.rawValue, forKey: "orientation")
                } else {
                    UIDevice.current.setValue(UIInterfaceOrientation.portrait.rawValue, forKey: "orientation")
                }
            }
        }
    }
    
    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool {
        return true
    }
    
    func application(_ application: UIApplication, supportedInterfaceOrientationsFor window: UIWindow?) -> UIInterfaceOrientationMask {
        return AppDelegate.orientationLock
    }
}

View

import SwiftUI

    struct CameraPage: View {
        var body: some View {
            ZStack {
                Color.black
                HStack {
                    Spacer()
                
                    Button {
                        
                    } label: {
                        Text("Capture")
                    }
                    .frame(width: 80, height: 80)
                    .background(Color.white)
                    .clipShape(Circle())
                }.padding(.trailing)
            }.onAppear {
                AppDelegate.orientationLock = .landscapeRight
            }
        }
    }

It changes the orientation to landscapeRight but do not lock the orientation if I hold my phone in potrait mode it again switches the camera view to the potrait mode why?

is it possible lock any view in desired orientation while using Swift UI?
