Cant add field to Taxonomy in graphql

[lotarbo]

Hello, i try to add field to Taxonomy type like in example https://statamic.dev/graphql#custom-fields

GraphQL::addField(TaxonomyType::NAME, 'terms', function () {
            return [
                'type' => GraphQL::string(),
                'resolve' => function () {
                    return 'test';
                }
            ];
        });

but it doesn't work.
Is there any reason why i can't add a field for the TaxonomyType ?

The TaxonomyType class isn't an interface, like entries, terms, assets, etc. You can only add fields to these interfaces:

cms/src/GraphQL/TypeRegistrar.php

Lines 66 to 71 in 45590ce

	PageInterface::addTypes();
	EntryInterface::addTypes();
	TermInterface::addTypes();
	AssetInterface::addTypes();
	GlobalSetInterface::addTypes();
	UserType::addTypes();
