Dismissing nested sheets

I am working on a video streaming service, the app allows users to select a video from the home page, this opens up a sheet that displays the video, some information, and other videos in the playlist. Users are able to tap one of the other videos in the playlist, and it opens a new video sheet over the current page. The user can continue to open up videos this way, causing a stack of sheets. I want the user to be able to dismiss one sheet, and have them all disappear. Here is a very basic mock up of how the app works

Code Block 
struct ContentView: View {
    @State var isShowing=false
    var body: some View {
        VStack{
        Button("Show Modal"){isShowing=true}
            .sheet(isPresented: $isShowing){
                modal_sheet(isShowing: $isShowing)
            }
        }
    }
}

Code Block 
struct modal_sheet: View {
    @Binding var isShowing : Bool
    @State var showingNext = false
    var body: some View {
        VStack{
            Button("Next Modal"){showingNext.toggle()}
                .sheet(isPresented: $showingNext, onDismiss: {isShowing=false}){
                    modal_sheet(isShowing: $isShowing)
                }
        }
    }
}

My idea was that setting the original boolean to false would hide the original sheet, which would also hide the rest of the sheets. If I only have 2 sheets open, this works, and dismissing the second sheet will also dismiss the first. If I have 3 or more sheets open, it will dismiss all sheets except for the first. I am relatively new to Swiftui so I am not sure if this is the way I should be handling the sheet dismissal. I would appreciate any tips on fixing this or any idea for a different way to handle the dismissal, thanks in advance!
