How can I access to a wrapped content in SwiftUI?

Question

I want to know how I can access to incoming wrapped content via ViewBuilder. As you can look for HStack or VStack in SwiftUI, they have same signature like MyContentView, with this deference that those views can look inside content for modifying them, let say adding space between them, or even alignment. So I am interested to know how apple-Stack`s can look inside incoming content? Then I can do same with my incoming content as well.

struct ContentView: View {
    var body: some View {
        MyContentView(content: {
            Text("Text 1")
            Text("Text 2")
            Text("Text 3")
        })
    }
}

struct MyContentView<Content: View>: View {
    @ViewBuilder
    let content: Content
    var body: some View {
        // Need to access to inside incoming content for more work ...
        content
    }
}
