Reset Session after payment success in ASP.Net Core

Hi,

I have a shopping site and after customer paid for the items the cart is empty but the number next to cart (how many items) is still the same and not reset to 0

the page after successful payment:

@model int
<h1>
    Your Order is Sucess, Your Order id is  @Model
</h1>

I am not sure where to put the code to reset the cart after purchase? at the start or login and logout I have the following:

<li class="nav-item">
    <a class="nav-link" asp-area="Customer" asp-action="Index"
    asp-controller="Cart">
@await Component.InvokeAsync("Cart")
</a>
</li>

and I have a folder (components/cart/Default.cshtml):

@model int
<i class="bi bi-cart"></i>(@Model)
