I have this structure of Schemas and I want to create a new Item in the array of items in the List which is an Item in the array of lists of an account. Thats how it looks:

const itemsSchema = new mongoose.Schema({
  name: String,
  creator: String
});

const Item = new mongoose.model("Item", itemsSchema);

///// List Schema /////
const listSchema = new mongoose.Schema({
  name: String,
  items: [itemsSchema],
  users: [String]
})

const List = new mongoose.model("List", listSchema)

///// Account Schema /////
const accountSchema = new mongoose.Schema({
  nickname: String,
  lists: [listSchema],
});
