Mongoose how to get property of related object by its id?

Question

MongoDB

There is a model GenreModel which contains two properties:
_id(created automatically) and genre_namestring type.
There is a Games model that contains:

game_name: { type: String, required: true, index: true},
game_genre: {type: mongoose.Schema.Types.ObjectId, ref: 'GenreModel', required: true }

The question is how to make game_genre not only have a GenreModel identifier, but also its genre_name property? That is, there must be an object with an identifier and its name.
