iBeacon with CLMonitor Slow

The other day I was playing with iBeacon and found out that CLBeaconIdentityConstraint will be deprecated after iOS 18.5. So I've written code with BeaconIdentityCondition in reference to this Apple's sample project.

import Foundation
import CoreLocation

let monitorName = "BeaconMonitor"

@MainActor
public class BeaconViewModel: ObservableObject {
	private let manager: CLLocationManager
	static let shared = BeaconViewModel()
	public var monitor: CLMonitor?
	@Published var UIRows: [String: [CLMonitor.Event]] = [:]
		
	init() {
		self.manager = CLLocationManager()
		self.manager.requestWhenInUseAuthorization()
	}
	
	func startMonitoringConditions() {
		Task {
			print("Set up monitor")
			monitor = await CLMonitor(monitorName)
			await monitor!.add(getBeaconIdentityCondition(), identifier: "TestBeacon")
			
			for identifier in await monitor!.identifiers {
				guard let lastEvent = await monitor!.record(for: identifier)?.lastEvent else { continue }
				UIRows[identifier] = [lastEvent]
			}
			
			for try await event in await monitor!.events {
				guard let lastEvent = await monitor!.record(for: event.identifier)?.lastEvent else { continue }
				
				if event.state == lastEvent.state {
					continue
				}
				UIRows[event.identifier] = [event]
				UIRows[event.identifier]?.append(lastEvent)
			}
		}
	}
	
	func updateRecords() async {
		UIRows = [:]
		for identifier in await monitor?.identifiers ?? [] {
			guard let lastEvent = await monitor!.record(for: identifier)?.lastEvent else { continue }
			UIRows[identifier] = [lastEvent]
		}
	}
	
	func getBeaconIdentityCondition() -> CLMonitor.BeaconIdentityCondition {
		CLMonitor.BeaconIdentityCondition(uuid: UUID(uuidString: "abc")!, major: 123, minor: 789)
	}
}

It works except that my sample app can take as long as 90 seconds to see event changes. You would get an instant update with an fashion (CLBeacon and CLBeaconIdentityConstraint). Is there anything that I can do to see changes faster? Thanks.
