How to create downloadable csv file from a javascript object consisting of array?

Question

I have an object like this:-

{
    "SUCCESS": [
        "apple",
        "orange",
        "grapes"
    ],
    "FAILED": ["kiwi"],
    "NOPE": ["peach"]
}

I want to have a CSV as follows:-

apple  SUCCESS
orange SUCCESS
grapes SUCCESS
kiwi   FAILED
peach  NOPE

I figured out this piece of code but unable to iterate over this:-

const downLoadCsv = (key, items) => {
    let csvContent = '';
    if (!items.length) {
      return;
    }
    items.forEach((item) => {
      csvContent += `${item},`;
      csvContent += '\n';
    });

    const anchorEle = document.createElement('a');
    anchorEle.href = `data:text/csv;charset=utf-8,${encodeURI(csvContent)}`;
    anchorEle.target = '_blank';
    anchorEle.download = `${key}.csv`;
    anchorEle.click();
  };
