Rounded corners and border for a SwiftUI List Section

I want to create the following design in SwiftUI. I am currently using a list and creating a section that contains cells like so.

List {
    Section {
        ForEach(titles) { title in
            Cell(title: title)
        }
    }
}

When I apply a modifier like a border to the section it applies it to all the views contained in the Section. I want to have that border around the entire Section with a corner radius of 10. The closest I have got to creating the desired design is by not using a List but instead using a VStack and applying the following modifiers

VStack {
    ForEach(titles) { title in
        Cell(title: title)
    }
}
.overlay(RoundedRectangle(cornerRadius: 10)
            .stroke(.gray, lineWidth: 2))

I discovered however that this is not a smart approach as the List uses reusable cells and in the case of VStack they do not. Is it possible to create the wanted design with a List in SwiftUI? I do not want to opt for the default list style provided by Apple

Just Copy paste this code and customise it as per your needs, enjoy

import SwiftUI

struct CustomizeListView: View {

var titles = ["First Section" : ["Manage your workout", "View recorded workouts", "Weight tracker", "Mediation"], "Second Section" : ["Your workout", "Recorded workouts", "Tracker", "Mediations"]]


var body: some View {
    List {
        ForEach(titles.keys.sorted(by: <), id: \.self){ key in
            Section(key) {
                VStack(alignment: .leading, spacing: 0){
                    ForEach(titles[key]!, id: \.self) { title in
                        HStack{
                            Text(title)
                            Spacer()
                            Image(systemName: "arrow.right")
                        }//: HSTACK
                        .padding(20)
                        Divider()
                    }//: LOOP
                }//: VSTACK
                .overlay(
                    RoundedRectangle(cornerRadius: 10, style: .circular).stroke(Color(uiColor: .tertiaryLabel), lineWidth: 1)
                )
                .foregroundColor(Color(uiColor: .tertiaryLabel))
            }//: SECTION
        }//: LOOP
    }//: LIST
    .listStyle(InsetListStyle())
}
}

struct CustomizeListView_Previews: PreviewProvider {
static var previews: some View {
    CustomizeListView()
}
}
