    }
}
```

public class YourService
{
    private readonly INotificationSender _notificationSender;

    public YourService(INotificationSender notificationSender)
    {
        _notificationSender = notificationSender;
    }

    public async Task SendSessionExpirationNotificationAsync(Guid userId)
    {
        await _notificationSender.SendAsync(
            IdentityNotificationNames.Session.ExpirationSession,
