Как запросить данные из вложенного документа в mongodb?

Я слишком много борюсь с этим вложенным документом. Я пытался прочитать документ, а также следовать другим ответам SO, чтобы узнать, работает ли он для меня, но я не получаю результатов, которые ищу. Я хочу извлечь некоторую информацию из большого вложенного документа.

ДАННЫЕ

Я загрузил данные на игровую площадку mongo. https://mongoplayground.net/p/7nbLtXMlFMx

Я хочу извлечь config из children of page, где имя company-information и description из имени company-hero. Я читаю статьи и документацию и могу делать что хочу, если документ не такой вложенный. Но я совершенно не понимаю, как извлечь ту информацию, которую я ищу. Я впервые работаю над Mongodb в такой степени. Раньше я делал что-то очень простое.

Я старался

db.collection.find(
    {"page.children.3.children.2.name": {"$eq": "company-information"}}, 
    {"page.children.3.children.2": 1}
) 

но получил пустой результат

Вывод

Есть около 1000 строк (? Не уверен, что я могу назвать это строками). Часть, которая меня интересует, это вытягивание page.children[3].children[2], где имя company-information. Итак, результат должен быть следующим:
