SwiftUI align navigationBarItems buttons with large navigationBarTitle like in "Messages" - ios

Question

I am creating a SwiftUI app and I am using NavigationView and a large title bar. However, I don't like that navigationBarItems buttons are not aligned with the large title bar (3rd picture) like in the Messages app (first and second picture). I tried to reposition the button, but it wasn't clickable anymore. Does anybody have an idea how to solve this? Thanks!

#State private var headerText = "Contacts"
var body: some View {
NavigationView {
List {
HStack {
//text

.frame(height: 40, alignment: .leading)
.padding(.top, 5)
.offset(x: -45)
HStack {
//button 1
Button(action: {
self.action1()
}) {
Image(systemName: "ellipsis.circle")
.font(.largeTitle)

}.padding(EdgeInsets(top: 5, leading: 0, bottom: 0, trailing: 16))
.foregroundColor(.blue)
} .frame(height: 40, alignment: .leading)
.opacity(self.midY < 70 ? 0.0 : 1.0)
.frame(alignment: .bottom)
ForEach(0..<100){ count in
Text("Row \(count)")

.navigationBarItems(leading:
Button(action: goBack) { HStack { Image("back") } })
.navigationBarItems(trailing: HStack {
Button(action: { self.share() }) { Image("share") }
Button(action: { self.wishlist() }) { Image("wishlist_detail") }})
