This article describes the available events in the Telerik Notification for Blazor:
OnClose
The TaskBoard OnClose event fires when a visible notification popup disappears as a result of a Close button click or the elapse of the CloseAfter timeout period.
The event handler receives a NotificationCloseEventArgs argument.

<TelerikButton OnClick="@ShowNotification">Show Notification</TelerikButton>

@code {
private TelerikNotification? NotificationRef;
private string NotificationEventLog { get; set; } = string.Empty;

NotificationRef?.Show($"Notification Text {Random.Shared.Next(1, 100)}", ThemeConstants.Notification.ThemeColor.Primary);
