Guidance on hovering button over scrollview

Question

Screenshot 2023-04-03 at 8 53 22 AM Hi,

Thank you for the wonderful software.

Using https://github.com/exyte/FloatingButton

The image above shows that the hstack containing the button does not float/hover.

How would I be able to have this hover over the scroll view as scroll occurs without the opaque background shown here?

Thank you

NavigationView{
  ScrollView(showsIndicators: false){
    Text("WELCOME TO")
      .padding(.top, 100)
      .font(.custom("SF Pro Display", size: 12))
    Text("object")
      .multilineTextAlignment(.center)
      .padding(.bottom, 50)
      .padding(.top, 5)
      .font(.custom("Lato", size: 26))
    VStack{
      HStack{
          Button(action: {
            showingATimesSheet.toggle()}) {

      HStack{

        Button(action: {

          Text("More features coming soon")
            .multilineTextAlignment(.center)
              .fixedSize(horizontal: false, vertical: true)
              .padding(EdgeInsets(top: (UIScreen.screenWidth)/6, leading: (UIScreen.screenWidth)/19, bottom: (UIScreen.screenWidth)/6, trailing: (UIScreen.screenWidth)/19))
              .background(Color.white)
        }
          .background(Color.white)
          .frame(width: UIScreen.screenWidth*2/5, height: UIScreen.screenWidth*2/5)
          .background(Color.white)
          .cornerRadius(7)
          .shadow(color: .gray, radius: 2, x: 0, y: 1)
          .foregroundColor(.black)
          .buttonStyle(.plain)
            .sheet(isPresented: $showingMoreFeaturesSheet) {
                MoreFeaturesView()
        }

      }
    }
    .frame(maxWidth: .infinity)
    .edgesIgnoringSafeArea(.all)
    .statusBar(hidden: true)
    .navigationBarTitle("")
    .navigationBarHidden(true)
  }
}
HStack{
  Spacer()
  FloatingButton(mainButtonView: MainButton(imageName: "cloud.fill", colorHex: "eb3b5a"), buttons: MockData.iconImageNames.enumerated().map { index, value in
    IconButton(imageName: value, color: MockData.colors[index])
  })
  .straight()
  .direction(.top)
  .delays(delayDelta: 0.1)
}

} }

I tried shuffling the Stacks around, and making a transparent view. No success.
