How to navigate after few seconds in SwiftUI?

Need some extra help with SwiftUI and navigating between views.

In one view, I have a button with ImagePicker:

.sheet(isPresented: $showingImagePicker, onDismiss: loadImageAndNavigate) {
    ImagePicker(image: $image, isShown: $showingImagePicker, sourceType: sourceType)
}

and when the user chooses or takes an image, on dismiss I want to show some spinner until image will be classified, and later to navigate and send this image to another view.

How can I navigate to another view from loadImageAndNavigate func?
