Mongodb update push Array of Objects - node.js

Question

I am unable to solve this issue (and looking to avoid loop update one by one), please hep me out here.
I have a fambio document (which has its own FamilyModel) which gets created after user gives his below information:
{
name: 'john',
lname: 'doe',
}
Now, after above information gets saved, user provides more information about the family after some processing in backend:
let familyArr = [
{ _id: 1234, name: 'Jenny', lname: 'doe', relation: 'mother' },
{ _id: 2345, name: 'Jawn', lname: 'doe', relation: 'father' },
{ _id: 3456, name: 'Jane', lname: 'doe', relation: 'sister' },
{ _id: 4567, name: 'Daisy', lname: 'wick', relation: 'pupper' }
]
Altogether, FamilyModel schema looks like:
const FamilyModel = mongoose.Schema({
name: {type: String, required: true},
lname: {type: String, required: true},
family: [relationshipSchema]
}, {
timestamp: true
});
const relationshipSchema = mongoose.Schema({
name: {type: String, required: true},
lname: {type: String, required: true},
relation: {type: String, required: true}
}, {
required: false,
timestamp: true
});
Now, John has an array of objects of family (filed type Array) and trying to insert that Array of Object like this:
What I tried multiple options:
db.fambio.updateOne({_id: 1111}, { $set: { family: familyArr }})
db.fambio.findOneAndUpdate({_id: 1111}, { $push: { family: familyArr }});
db.fambio.update({_id: 1111}, $addToSet: { 'family': familyArr}});
Nothing is working with respect to insert the constructed Object directly to the field. When I insert one at a time, it gets updated.
How am I supposed to write the query to update/append an Array of Objects in to a field of Array Type having its own Schema maintained.

Okay, I've solved it. How I solved it:
Initially, I saved the document and did some processing on the info as per my requirements post which I wanted to insert Array of Elements in to an Array key field where I was running in to the issue of nothing getting inserted. What I was missing was $each and this is how I did it:
db.getCollection('fambio').update({
_id: johnsuserid
}, {
$push: {
'family': {
$each:[
{ _id: 1234, name: 'Jenny', lname: 'doe', relation: 'mother' },
{ _id: 2345, name: 'Jawn', lname: 'doe', relation: 'father' },
{ _id: 3456, name: 'Jane', lname: 'doe', relation: 'sister' },
{ _id: 4567, name: 'Daisy', lname: 'wick', relation: 'pupper' }
]
}
}
});
Thank you everyone!! Hope this helps someone who may face this problem in future.
