Clear background for form sections in SwiftUI?

Question

I'm trying to remove the white background of some sections so the elements lay right on the grey background, but I can't get the section background to be removed or transparent.

This is what I'm trying:

struct ContentView: View {
    
    var body: some View {
        Form {
            Section {
                Text("Hello!")
                Button {
                    print("Clicked")
                } label: {
                    Text("Click Me!!")
                }
            }
            Section {
                VStack {
                    Button("Button 1") {}
                    Spacer()
                    Button("Button 2") {}
                }
            }
            .background(Color.clear) // Not doing anything
            Section {
                VStack(alignment: .leading) {
                    Text("Location")
                        .font(.headline)
                    Group {
                        Text("Abc")
                        Text("Abc")
                        Text("Abc")
                    }
                    .font(.caption)
                }
            }
        }
    }
}

This is what it looks like:

I tried to add .background(Color.clear) to the Section and VStack, but it did not have any effect. How an this be achieved in SwiftUI?

Even in SwiftUI 2 Form is built on top of UIKit, specifically UITableView.

You need to remove the default UITableViewCell's background (only once, preferably in the App init):

UITableViewCell.appearance().backgroundColor = UIColor.clear

and change the background using:

Section {
    VStack {
        Button("Button 1") {}
        Spacer()
        Button("Button 2") {}
    }
}
.listRowBackground(Color.clear)
