How to flatten a array of object having subRows inside?

I have an array of object and have to convert in level 1 json (flatten) it. The keys code and takenBY are dynamic

key1 = "code",
key2 = "takenBy"

const dataObject = [
    {
        "code": "ABCD",
        "subRows": [
            {
                "takenBy": "Ram",
                "workedAccounts": 2,
                "contactableAccounts": 1,
            },
            {
                "takenBy": "krish",
                "workedAccounts": 2,
                "contactableAccounts": 2,
            }
        ],
        "workedAccounts": 4,
        "contactableAccounts": 3,
    },
    {
        "code": "XYZ",
        "subRows": [
            {
                "takenBy": "Jack",
                "workedAccounts": 5,
                "contactableAccounts": 0,
            },
            {
                "takenBy": "krish",
                "workedAccounts": 4,
                "contactableAccounts": 4,
            }
        ],
        "workedAccounts": 9,
        "contactableAccounts": 4,
    },
]

const headerObject = [
    { label: 'Code', field_key: 'code' },
    { label: 'Worked Accounts', field_key: 'workedAccounts' },
    { label: 'Contactable Accounts', field_key: 'contactableAccounts' },
    { label: 'Taken By', field_key: 'takenBy' },
];

const result = [
    {
        "Code": "ABCD",
        "Taken By": "",
        "Worked Accounts": 4,
        "Contactable Accounts": 3,
    },
    {
        "Taken By": "Ram",
        "Worked Accounts": 2,
        "Contactable Accounts": 1,
    },
    {
        "Taken By": "krish",
        "Worked Accounts": 2,
        "Contactable Accounts": 2,
    },
    {
        "Code": "XYZ",
        "Taken By": "",
        "Worked Accounts": 9,
        "Contactable Accounts": 4,
    },
    {
        "Taken By": "Jack",
        "Worked Accounts": 5,
        "Contactable Accounts": 0,
    },
    {
        "Taken By": "krish",
        "Worked Accounts": 4,
        "Contactable Accounts": 4,
    }
];

const result = dataObject .reduce((acc, { subRows, ...rest }) => acc.concat(subRows.map(({ ...props }) => ({ ...props, ...rest}), [])), []);
