SwiftUi TabView icon size and margin

Question

I've created an basic app with swiftui that contain a bottom tab navigation menu.

I've a question, it's possible to increase the margin top of the icon? and it's possible to decrease the icon size? this is my code:

var body: some View {
        TabView {
            MarketplaceView()
                .tabItem {
                    Label("", systemImage: "arrow.right.arrow.left")
                        .environment(\.symbolVariants, .none)
                }
            WalletView()
                .tabItem {
                    Label("", systemImage: "creditcard")
                        .environment(\.symbolVariants, .none)
                }
            My11View()
                .tabItem {
                    Label("", systemImage: "person.3")
                        .environment(\.symbolVariants, .none)
                }
            NotificationCenterView()
                .tabItem {
                    Label("", systemImage: "bell")
                        .environment(\.symbolVariants, .none)
                }
            ProfileView()
                .tabItem {
                    Label("", systemImage: "person")
                        .environment(\.symbolVariants, .none)
                }
        }
        .accentColor(Color("m_green"))
    }

thanks!
