MongoDB – db.save()- Type Error- db.collection.save is not a function

When I try to make a save function, then it goes an error.
ie. I tried db.collection.save()
my db is test and my collection name is myCol

test> db.myCol.find()
[
  {
    _id: ObjectId("62dd5dfd976a6f6126179768"),
    name: 'J',
    totVal: 5,
    values: [ 'Hi', 'Hello', 'How' ],
    valMin: 15
  },
  {
    _id: ObjectId("62dd738a976a6f6126179769"),
    name: 'K',
    values: [ 'Hi', 'Hello', 'How' ],
    totVal: 5,
    valMin: 15
  }

    It's done using this: Beacause- save is depricated and use replaceOne() instead of save().

    db.myCol.replaceOne({"_id": ObjectId("62dd738a976a6f6126179769")},{"name":"New Element"})

    Ensure that your myCol schema defines _id:

    const myCol = Schema({
  _id: Schema.Types.ObjectId,
  name: String,
  totVal: Number,
  values: [String],
  valMin: Number
});
