Button Labels in MenuBarExtra not showing images/icons

As the title suggests, the icons/images in labels are not appearing in the MenuBarExtra

Here is the code I'm running:

import Combine
import SwiftUI

class TimerViewModel: ObservableObject {
    private var assignCancellable: AnyCancellable? = nil

    @Published var somelist: Array<String> = ["default"]

    init() {
        assignCancellable = Timer.publish(every: 5.0, on: .main, in: .default)
            .autoconnect()
            .map { String(describing: $0) }
            .assign(to: \TimerViewModel.somelist[0], on: self)
    }
}

@main
struct mbe_testingApp: App {
    @State var clickCount = 0
    @ObservedObject var timerOutput = TimerViewModel()

    var body: some Scene {
        MenuBarExtra("mbe test", systemImage: "\(clickCount).circle") {
            Button() {
                clickCount += 1
                print("incremented")
            } label: {
                Label("Increment", systemImage: "plus.square.fill")
            }

            Button() {
                if clickCount > 0 {
                    clickCount -= 1
                }
                print("decremented")
            } label: {
                Label("Decrement", systemImage: "minus.square.fill")
            }

            Button() {
                print("clicked")
            } label: {
                Label(timerOutput.somelist[0], systemImage: "clock")
            }
        }
    }
}

which results in a menu that looks like:

What am I missing to make the label images appear alongside the text on the menu buttons?
