Blazor Allow Anonymous For Razor Page-CodePudding

I have a .net cor 3.1 Blazor server project. I use the default identity system in this project. I want to access a specific razor page without login. How do I do that? Any Idea?

I tried adding @attribute [AllowAnonymous] to the razor page. But it did not work for me

_Host.cshtml

page "/"
@using Microsoft.AspNetCore.Authorization
@namespace has.Pages
@addTagHelper *, Microsoft.AspNetCore.Mvc.TagHelpers
@attribute [Authorize]
@{
    Layout = null;
}

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="utf-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <title>has</title>
