Query all site languages

I try to make a select field where users can choose one of the site’s available languages.

 default_lang:
        label:
          ru: Язык по умолчанию
          en: Default language
        type: select
        width: 1/2
        options: query
        query: 
          fetch: kirby.languages
          text: "{{ language.name }}"
          value: "{{ language.code }}"

As a result, I see a select field with a correct number of options, but instead of an option text and value I see exactly my query code {{ language.name }}.

Should be:

  fetch: kirby.languages
    text: "{{ item.name }}"
    value: "{{item.code }}"
