Menu is not translatable resources?

Hi. I’m Japanese developer.

I’m using Storefront Api with Hydrogen.

By using Translate & Adapt, product and page could be responded with translated results.

But menu could not be translated.

Then, I found the document about translatable resources, but menu is not included.

https://shopify.dev/custom-storefronts/internationalization#translatable-resources

Is it true?

Please tell me how to translate menu if there is any way.
