I like to use the built-in C:\Windows\Microsoft.NET\Framework64\v4.0.30319. I can create local notifications using Microsoft.Toolkit.Uwp.Notifications.dll or CommunityToolkit.WinUI.Notifications.dll via Assembly.Load(), GetType() and InvokeMember(). But I can't set the lifetime of the notification. I can't get in touch with my notifications in the notification center to delete the notification without activation. There are no examples anywhere. Is it possible to do this? Can you give me an example like this? For example, you can display a simple notification like this:

Assembly a = Assembly.Load("CommunityToolkit.WinUI.Notifications");
Type b = a.GetType("CommunityToolkit.WinUI.Notifications.ToastContentBuilder");
dynamic o = new dynamic[1];
o[0]=Activator.CreateInstance(b,BindingFlags.Instance|BindingFlags.Public|BindingFlags.CreateInstance|BindingFlags.NonPublic, null, new object[]{}, null);
o[0].Show();

And how to kill it after 1 minute is not known :-(
