How can I create a folder using a rectangle in SwiftUI?

I'm currently working on an app and I want to create some kind of folders for it, I don't want to work with an image, so I want to do it with rectangles, but I'm afraid I'm not that clever, so I'm asking here if you can help me with this.

Many thanks in advance.

This is my current code:

ZStack{
            
            VStack{
                RoundedRectangle(cornerRadius: 25)
                    .fill(Color("marineblau"))
                    .frame(width: 100, height: 80)
            }
            
            VStack{
                RoundedRectangle(cornerRadius: 25)
                    .fill(Color("blau"))
                    .frame(width: 150, height: 110)
            }
        }

like this ?

    ZStack{

            RoundedRectangle(cornerRadius: 5)
                .fill(.black) // Change the color
                .frame(width: 60, height: 80)
                .offset(x: -45, y: -30)

            RoundedRectangle(cornerRadius: 10)
                .fill(.black) // Change the color
                .frame(width: 150, height: 80)
                .offset(y: -25)


            RoundedRectangle(cornerRadius: 10)
                .fill(.blue)  // Change the color
                .frame(width: 150, height: 110)

        VStack {
            Image(systemName: "chart.bar.xaxis.ascending")
            Text("Name")

        }
        .font(.title3.bold())
        .foregroundStyle(.white)

    }

or like this :

    ZStack{

            RoundedRectangle(cornerRadius: 5)
                .fill(.black) // Change the color
                .frame(width: 60, height: 80)
                .offset(x: -45, y: -32)
                .overlay(
                    Path { path in
                        path.move(to: CGPoint(x: 0, y: 50))
                        path.addLine(to: CGPoint(x: 0, y: 0))
                        path.addLine(to: CGPoint(x: 50, y: 50))
                        path.closeSubpath()
                    }
                        .fill(Color.black)
                        .offset(x: 12, y: -32)
                )

            RoundedRectangle(cornerRadius: 10)
                .fill(.black) // Change the color
                .frame(width: 150, height: 80)
                .offset(y: -25)

            RoundedRectangle(cornerRadius: 10)
                .fill(.blue)  // Change the color
                .frame(width: 150, height: 110)

        VStack {
            Image(systemName: "chart.bar.xaxis.ascending")
            Text("Name")

        }
        .font(.title3.bold())
        .foregroundStyle(.white)

    }
