Enum object syntax does not work on a number path

What is the current behavior?
According to mongoose docs there are two ways to set a validator message: using array syntax or using object syntax.

Currently, the enum object syntax is not working on a number path.

If the current behavior is a bug, please provide the steps to reproduce.

const { Schema, model } = require('mongoose');

const reviewSchema = new Schema({
  comment: String,
  rating: {
    type: Number,
    enum: {
      values: [1, 2, 3, 4, 5],
      message: 'Rating must be an integer between 1 and 5',
    },
  },
});

const Review = model('Review', reviewSchema);

const review = new Review({ comment: 'Excellent!', rating: 5 });

console.log(review.validateSync());

Causes the error:

Error: Review validation failed: rating: `5` is not a valid enum value for path `rating`.

What is the expected behavior?
To be able to use object syntax to set an enum validator for numbers.

What are the versions of Node.js, Mongoose and MongoDB you are using? Note that "latest" is not a version.
Node.js: v14.17.3
Mongoose: v6.0.3
MongoDB: irrelevant

Only strings have the enum property. For Numbers it is min and max

Then the docs are wrong: https://mongoosejs.com/docs/schematypes.html#number-validators

I'm getting the same error message

const mongoose = require('mongoose');
const { Schema, model } = mongoose;

const reviewSchema = new Schema({
  comment: String,
  rating: {
    type: Number,
    enum: {
      values: [1, 2, 3, 4, 5],
      message: 'Rating must be an integer between 1 and 5',
    },
  },
});

const Review = model('Review', reviewSchema);
async function test() {
    await mongoose.connect('mongodb://localhost:27017/test', {
        useNewUrlParser: true,
        useUnifiedTopology: true,
      });
      await mongoose.connection.dropDatabase();

      const review = new Review({ comment: 'Excellent!', rating: 5 });

    console.log(review.validateSync());
}

test();
