Edit nested values by relational _id in mongoose - node.js

Question

Hello I have relational _ids in an array. The object content is in other collection. I can only view Object("_id") in my array.
I want to edit object of those _ids. How can I edit by using relational _ids ??
I have data response like this
{
"admins": {
"users": [
"5d089739d8aae228d7f10c1e" //<------ edit this id object
],
"email": "jertacomlu#desoz.com",
"password": "$2a$10$C/DsmoHK57vIUt7g4wRsYulHLigmc1wGLObwu2/qkFkSeYp28bAOy",
},
"_id": "5d089264d8aae228d7f10c1d",
"companyName":"Company 1",
"__v": 0
}
So this id is stored in other collection name Userr.
the object is like this:-
[ {
"_id": "5d089739d8aae228d7f10c1e",
"email": "jertacomlu#desoz.com",
"password": "$2a$10$0Slx3yFeb7UD0qep.TWSI.JpQGl0CzlGhNJ162JtA5Uvt6osyrIl.",
"firstName": "Sima",
"lastName": "Cezo",
"phoneNumber": "8877123456",
"__v": 0
}
]
I want to edit these fields. How can I do by using relation _id ?
EDIT:-
my parent controller
var admin = new Admin();
admin.companyName = req.body.companyName;
admin.admins = {
email : req.body.email,
password: req.body.password,
role : "admin",
verified :"false",
active: "OFF",
users : []
};

Answer 1

admin.find({id:"5d089264d8aae228d7f10c1d"}).populate("users").then(data=>{
//update the fields which you would find in the data object
data.save()
//your data would be changed.
})

Answer 2

You must create a method at model User , example to edit email :
User.edit=async function (id,newEmail){
let user = await User.findOne({_id:id}).exec();
user.email=newEmail;
await user.save();
}
In Admin ,
...
let admin = await Admin.findOne({_id:id}).exec();
await User.edit(admin.users[0])
...
