Products per category

[trouble2]

I am wondering if it is possible to create a category menu with the number of products in it.
I asked my friend chat GPT but that did not really end well :-)
It suggested something like this:
@inherits NBrightBuy.render.NBrightBuyRazorTokens<NBrightDNN.NBrightRazor>
@using System.Linq
@using Nevoweb.DNN.NBrightBuy.Components

@{
var grpcat = (GroupCategoryData)Model.List.First();
var depth = grpcat.depth;
//this does not work
var count = grpcat.productcount;
}

@if (grpcat.url.StartsWith("javascript"))
{

@grpcat.categoryname (@count)

}
else
{

@grpcat.categoryname (@count)

}
