Disable/enable local notifications on Android and iOS

I have implemented repetitive local notification system like below:

 AndroidNotificationChannel notificationChannel = new AndroidNotificationChannel ()
 {
   Id = "test_reminder_channel",
   Name = "Test Reminder Channel",
   Description = "Reminder notifications",
   Importance = Importance.High,
 };
 AndroidNotificationCenter.RegisterNotificationChannel (notificationChannel);
    
 AndroidNotification notification = new AndroidNotification
 {
     Title = "Reminder from Test",
     Text = "Turn daily Wheel of Luck",
     FireTime = DateTime.Now.AddSeconds (5),
     RepeatInterval = new TimeSpan (0, 0, 5),
     ShouldAutoCancel = true,
     SmallIcon = "icon_small",
     LargeIcon = "icon_large"
 };            
 AndroidNotificationCenter.SendNotification (notification, notificationChannel.Id);

Now I need to disable or enable notifications from settings menu. How can I achieve this? Any help appreciated. Thanks
