New developer to Umbraco implementation.

Trying to implement the MeganavV8.

I started here: https://our.umbraco.com/packages/website-utilities/meganavv8/

I created the MegaNav DataType to add to a composition so that I could add it to my HomePage for easy management.

I'm able to create the links - including nested no issue.

My problem comes on the partial view - see code:

@inherits Umbraco.Cms.Web.Common.Views.UmbracoViewPage
@using Umbraco.Cms.Core
@using Umbraco.Cms.Core.Models.PublishedContent
@using Umbraco.Cms.Core.Routing
@using Umbraco.Extensions

@inject IPublishedValueFallback PublishedValueFallback
@inject IPublishedUrlProvider PublishedUrlProvider

    <!-- Navigation -->

@{
    var homePage = Umbraco.AssignedContentItem.AncestorOrSelf<HomePage>();

}

<nav class="navbar navbar-expand-lg navbar-light" id="mainNav">
            <div class="container px-4 px-lg-5">
                <a class="navbar-brand" href="@homePage.Url()">Site Name</a>
                <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarResponsive" aria-controls="navbarResponsive" aria-expanded="false" aria-label="Toggle navigation">
                    Menu
                    <i class="fas fa-bars"></i>
                </button>
                <div class="collapse navbar-collapse" id="navbarResponsive">

                    <ul class="navbar-nav ms-auto py-4 py-lg-0">

                                @foreach (var item in Model.Value<IEnumerable<MeganavV8Item>>("megaNavV8"))
                                {
                                 <li class="nav-item"><a class="nav-link px-lg-3 py-3 py-lg-4" href="@item.Link.Url">@item.Title</a></li>
                                }        



                    </ul>

                </div>
            </div>
        </nav>

When I run and refresh, I get the following error:

The type or namespace name 'MeganavV8Item' could not be found (are you missing a using directive or an assembly reference?)
+
                                @foreach (var item in Model.Value<IEnumerable<MeganavV8Item>>("megaNavV8"))

Keep in mind I am new to the implementation and have limited experience with razor code - can anyone tell me what I am doing wrong? What am I missing? Or can anyone point me to a tutorial with instructions and code examples so that I can teach myself?

I'm finding that there is limited documentation don't the implementation of this tool... so it's been challenging, to say the least.

Thanks in advance for the assistance!
