Project Structure: Blazor Automode, .Net 8

To create a page in a blazor project you use:

@page "yourUrl"

I want to create my own page attribute for the exact permissions to be able acess a page like:

@page "/user/crud"
//this line below is what i believe it would be, but currently does not work
@permissions "[userRead, userWrite]"

Does exists a way to make it work? If so, how?

I’ve tried researching but the only seggestion i found was:

using System;

[AttributeUsage(AttributeTargets.Class, Inherited = false, AllowMultiple = false)]
public class MyCustomAttribute : Attribute
{
    public string Title { get; set; }
}

@MyCustomAttribute(Title = "My Custom Page Title")
@page "/my-page"

<h1>Welcome to my custom page!</h1>

But basically does not work.
