jql查询语法

const user = await uIdUser.field('_id,nickname').getTemp()
const kehu = await db.collection('crm-kehu').where(matchObj).getTemp()
res = await db.collection(kehu, user)
.orderBy('create_date desc')
.skip((params.pageIndex - 1) * params.pageSize)
.limit(params.pageSize)
.get({
getCount: true
});

返回数据：
"_id": "67c15b727ae708a346cc42de",
"clientName": "陈总",
"lxRen": "",
"phone": "13757907274",
"cjRenId": [{
"_id": "668f7c21f2949c511f5a3f03",
"nickname": "张三"
}],
"fuZeRenId": [{
"_id": "668f7c21f2949c511f5a3f03",
"nickname": "李四"
}],

怎么把cjRenId中nickname重命名cjRenName, fuZeRenId中的nickname重命名fuZenRenName
