I have a background image in a ZStack where a List is in front of it. Now the list view is overlapping with a white background the image but I want it transparent.

ZStack {
   Image("background")
   .resizable()
   .ignoresSafeArea()
   .scaledToFill()
                
   VStack {
       List {
           ForEach(challenges) { challenge in
               HStack {
                    VStack {
                        Text(challenge.name ?? "")
                        .font(.title)
                    }
               }
           }
       }
   }
}
