Solution

You can ask your back-end team to provide values in a defined key names. Still you can do,

Object.keys(decodedObj).forEach(function (key) {
    let res = key.split("/");
    if (res.length > 1) {
        if (res[length - 1] === 'role') {
            // decodedObj[key] will be your role
        }
        // here you will get role, emailaddress, name, nameidentifier
    }
});

Let me know if this helps.
