Looking for a way to query for the Wishlist and private messaging in nopCommerce 4.2

Hello,

I am working on a single page theme for nopCommerce4.2.  I was able to get the  user Authentication like this:
@{
@using Nop.Core.Domain.Customers
var isAuthenticated = Nop.Core.Infrastructure.EngineContext.Current.Resolve<Nop.Core.IWorkContext>().CurrentCustomer.IsRegistered();
}

I would also like to be able to query for the Private Message and Wishlist as well, but can't find the proper method to call for them.  Any ideas on getting those values for a query?

            @if (AllowPrivateMessages)
            {
                <li>
                    <a href="@Url.RouteUrl("PrivateMessages", new { tab = "" })" class="ico-inbox">
                        <span class="inbox-label">@T("PrivateMessages.Inbox")</span>
                        <span class="inbox-unread">@Model.UnreadPrivateMessages</span>
                    </a>
                </li>
            }
            @if (WishlistEnabled)
            {
                <li>
                    <a href="@Url.RouteUrl("Wishlist")" class="ico-wishlist">
                        <span class="wishlist-label">@T("Wishlist")</span>
                        <span class="wishlist-qty">@T("Wishlist.HeaderQuantity", Model.WishlistItems)</span>
                    </a>
                </li>
            }

So this code is from nopCommerce42\Presentation\Nop.Web\Views\Shared\Components\HeaderLinks\Default.cshtml
The values for those fields in the model are populated in PrepareHeaderLinksModel()
in nopCommerce42\Presentation\Nop.Web\Factories\CommonModelFactory.cs
