Programmatically adding a new tax class into "Additional tax classes" in WooCommerce

I'm trying to programmatically add a new tax class in WooCommerce from my custom plugin. I want to achieve the same functionality as adding a new tax rate class from "Additional tax classes" under "WooCommerce -> Settings -> Tax" but programmatically. A new section next to the default ones "Tax options | Standard rates | Reduced rate rates | Zero rate rates" must appear with my new class and the functionality must be the same as Standart rates, Reduced rate rates etc... A table where I can add different rates for different countries. I tried achieving this through WC_Tax class but without success:

function wm_add_additional_rate_tax_classes() {
    $silver_rates = WC_Tax::create_tax_class('Silver Metal', 'silver-metal-tax-rates');
    $platinum_rates = WC_Tax::create_tax_class('Platinum Metal', 'platinum-metal-tax-rates');
    $palladium_rates = WC_Tax::create_tax_class('Palladium Metal', 'palladium-metal-tax-rates');
}
add_action( 'init', 'wm_add_additional_rate_tax_classes' );

It's adding new tax rate classes and they appear next to "Tax options | Standard rates | Reduced rate rates | Zero rate rates" but when I click on any of them there is no interface for adding tax rates for different countires. Any idea how to achieve this?

Your code should work as expected, maybe the bug is related to cache or something? Try this:

WC_Cache_Helper::invalidate_cache_group('taxes');

I don't know the reason of your problem. This code shows tax class with UI in dashboard, when pasted directly to functions.php:

function add_additional_rate_tax_classes()
{
    $tax_class_name = 'sample-tax-class';
    $tax_class_slug = 'sample-tax-class';
    $tax_class = WC_Tax::create_tax_class($tax_class_name, $tax_class_slug);
}

add_action('init', 'add_additional_rate_tax_classes');
