I’m using Mongoose with TypeScript and TypeScript is not able to infer that subdocuments have an _id field.

I’ve two Mongoose models:

// User.ts

export const UserSchema = new Schema({
    email: { type: String, required: true }
});

export default model('User', UserSchema);

// Score.ts

export const ScoreSchema = new Schema({
    score: { type: Number, required: true },
    owner: { type: UserSchema, required: true },
});

export default model('Score', ScoreSchema);

This is the code that uses the Score model:

const score = await Score.findById(id);
if (score.owner._id.toString() === adminId) { // TypeScript error occurs here: field `_id` doesn't exist
    console.log("Admin mode");
}

Field _id does exist on the object returned by findById. How can I setup Mongoose/TypeScript/my schemas so that this error disappears.
