有没有办法把阿波罗类型的守卫从包裹里拿出来？

Question

我看到我想在我的应用程序中使用阿波罗类型的卫士，它是

export function isField(selection) {
    return selection.kind === 'Field';
}

它位于node_modules/@apollo/client/utilities/graphql/storeUtils.js。但我不能只是将它导入到我的文件中，因为库似乎没有导出它，如果我只是粘贴import { isField } from '@apollo/client/utilities/graphql/storeUtils';，我会得到这个错误：

/Users/vorant94/git/github/vorant94-server/node_modules/@apollo/client/utilities/graphql/storeUtils.js:1
import stringify from 'fast-json-stable-stringify';
^^^^^^

那么有没有办法在lib之外使用它呢？

我需要简单地安装apollo-utilities包...
