从 API 请求中解构并返回以奇怪结构发现的数据

与这个有一段艰难的时光。我一直在寻找，但似乎没有找到类似的场景......

我正在尝试查找用户拥有的每个集合的作者。

我已经制作了这个函数来从 api 中提取数据，在这种情况下，一个特定的用户是质子，如链接末尾所示：

function BCAd() {
  const [bcOwner, setBcOwner] = useState<any>();

  useEffect(() => {
    async function fetchData() {
      const res = await fetch(
        'https://proton.api.atomicassets.io/atomicassets/v1/accounts/proton'
      );
      const { data } = await res.json();
      setBcOwner(data);
    }
    fetchData();
  }, []);

  if (!bcOwner) {
    return (
      <div>
        <Spinner />
      </div>
    );
  }

  console.log(bcOwner);

  return null;
}

export default BCAd;

问题是当我 consol.log bcOwner时，作者在一个数组（集合）内，该数组在另一个数组（0）内，在一个对象（集合）内......所以我需要进入集合和然后在每个0中，然后是收集以获取作者（这句话不是必需的，但我输入它以确保我得到我正在做的事情，哈哈）。我需要为 0,1,2 执行此操作......用户有多少。一旦我有了那个作者，我想返回所有这些作者并删除空值。解决这个问题的最简单方法是什么？

编辑：这是 console.log 字符串
