Custom ConfigureOptions is not changing set options when Configure is called

I'm trying to create a custom ConfigureOptions class implementing IConfigureNamedOptions in .NET 4.8.

Here is the implementation

public class ConfigureAppSettings : IConfigureNamedOptions<AppOptions>
{
    private readonly IConfiguration configuration;

    public ConfigureAppSettings()
    {
        configuration = new ConfigurationBuilder().BuildAdapterConfiguration("appsettings.json");
    }

    public void Configure(AppOptions options)
    {
        Configure(nameof(AppOptions), options);
    }

    public void Configure(string name, AppOptions options)
    {
        IOptions<AppOptions> configurationOptions = Options.Create(configuration.GetSection(nameof(AppOptions)).Get<AppOptions>());
        options = configurationOptions.Value;
    }
}

When configuring the dependency injection container the services.ConfigureOptions<ConfigureAppSettings>(); is called.

But then, when I want to use IOptionsSnapshot<AppOptions>, Value is null.

While debugging options is set inside the Configure method but when exists it, options reference is not preserved and is null.

How can I get the value set in Configure method?

Side note: I need this implementation because on Configure method I also need to call an HTTP service to the some options properties.
