It is possible to generate a new ObjectId using "mongoose.Schema.Types.ObjectId".

In fact, this is a common way to create a new ObjectId in Mongoose. When defining a schema in Mongoose, you can create a field of type ObjectId like this:

const userSchema = new mongoose.Schema({
  name: String,
  email: {
    type: String,
    required: true,
    unique: true,
  },
  password: String,
  createdAt: {
    type: mongoose.Schema.Types.ObjectId,
    default: mongoose.Types.ObjectId,
  },
})

Here, the createdAt field is of type ObjectId and has a default value generated by mongoose.Types.ObjectId.

So, it is definitely possible to generate a new ObjectId using "mongoose.Schema.Types.ObjectId".
