CLMonitor Beacon Example is Nonfunctional

I have used this example to create the following code:

import Foundation
import CoreLocation

let monitorName = "BeaconMonitor"
let testBeaconId = UUID(uuidString: "EDFA3FFA-D80A-4C23-9104-11B5B0B8E8F3")!

@MainActor
public class ObservableMonitorModel: ObservableObject {
    private let manager: CLLocationManager
    
    public var monitor: CLMonitor?
    
    init() {
        self.manager = CLLocationManager()
        self.manager.requestWhenInUseAuthorization()
        self.manager.requestAlwaysAuthorization()
    }
    
    func startMonitoringConditions() {
        Task {
            monitor = await CLMonitor(monitorName)
            await monitor!.add(getBeaconIdentityCondition(), identifier: "Beacon")
            
            for identifier in await monitor!.identifiers {
                guard let lastEvent = await monitor!.record(for: identifier)?.lastEvent else { continue }
                print(identifier, lastEvent.state)
            }
            
            for try await event in await monitor!.events {
                print("Event", event.identifier, event)
                
            }
        }
    }
    
}

func getBeaconIdentityCondition() -> CLMonitor.BeaconIdentityCondition {
    CLMonitor.BeaconIdentityCondition(uuid: testBeaconId)
}

Unfortunately, running this on my iPhone only prints "Beacon CLMonitoringState". I don't see anything from the for try await block starting with "Event".

Any ideas where I've gone wrong?
