Issues with Commerce Abandoned Cart implementation

Hi there.

I’m trying to hook up the abandoned cart email to our external email provider (SendGrid). I’ve followed the documentation for setting up the Abandoned Carts Notification, and I found the CartAbandonedNotification, so I created a handler:

public class UmbracoAbandonedBasket : NotificationEventHandlerBase<CartAbandonedNotification>
{
private readonly IServiceProvider _serviceProvider;

public UmbracoAbandonedBasket(IServiceProvider serviceProvider)
{
    _serviceProvider = serviceProvider;
}

public override void Handle(CartAbandonedNotification evt)
{
    using var scope = \_serviceProvider.CreateScope();
    var orderService = scope.ServiceProvider.GetRequiredService<IOrderService>();
    var emailService = scope.ServiceProvider.GetRequiredService<IEmailService>();
    var siteSettingsService = scope.ServiceProvider.GetRequiredService<ISiteSettingsService>();
    var logger = scope.ServiceProvider.GetRequiredService<ILogger<UmbracoAbandonedBasket>>();


    foreach (var orderId in evt.OrderIds)
    {
        //send abandoned cart email asynchronously without awaiting
        var task = ProcessAbandonedCart(orderId, orderService, emailService, siteSettingsService, logger);
    }
}

DI:

            umbracoCommerceBuilder.WithNotificationEvent<CartAbandonedNotification>()
            .RegisterHandler<UmbracoAbandonedBasket>();

The issue is that the class above never runs. Umbraco Commerce continues using its built-in abandoned cart email handler.

Is there a way to override or replace the default implementation so I can plug in my own SendGrid based email logic? I suspect I may be approaching this the wrong way.

Thanks a lot for your help!
