I am trying to use an EditForm in an application with authentication and authorization working correctly. When I tried to submit an EditForm, I get this error:

A valid antiforgery token was not provided with the request. Add an antiforgery token, or disable antiforgery validation for this endpoint.

I have done the following in the Program.cs file:

builder.Services.AddAntiforgery(options =>
{
    options.FormFieldName = "AntiforgeryFieldname";
    options.HeaderName = "X-CSRF-TOKEN-HEADERNAME";
    options.SuppressXFrameOptionsHeader = false;
    options.Cookie.HttpOnly = true;
    options.Cookie.SameSite = SameSiteMode.Strict;
    options.Cookie.IsEssential = true;
    options.Cookie.SecurePolicy = CookieSecurePolicy.None;
});
// . . . 
// . . . 
app.UseAntiforgery();

In my EditForm on a Blazor component page, I have:

<EditForm method="post" Model="Membership" OnValidSubmit="AddMembership" FormName="create" Enhance>
     <DataAnnotationsValidator />
     <ValidationSummary class="text-danger" />
     <input typeof="hidden" id="AntiforgeryFieldname"/>

I am not sure what I did wrong. Before implementing authentication and authorization, the EditForm worked correctly.

I expected this to work based on the Microsoft documentation.
