NestJS - How to create nested schema with decorators

Question

Let's say I want to build the below schema with mongoose:

const userSchema = new Schema({
  name: {
    firstName: String,
    lastName: String
  }
})

How can I do it with NestJS decorators (@Schema() & @Prop())?

I try this method, but no luck:

@Schema()
class Name {
  @Prop()
  firstName: string;

  @Prop()
  lastName: string;
}

@Schema()
class User extends Document {
  @Prop({ type: Name })
  name: Name;
}

I also don't want to use the raw() method.

Here's my method which works great and doesn't involve removing @schema():

// Nested Schema
@Schema()
export class BodyApi extends Document {
  @Prop({ required: true })
  type: string;

  @Prop()
  content: string;
}
export const BodySchema = SchemaFactory.createForClass(BodyApi);

// Parent Schema
@Schema()
export class ChaptersApi extends Document {
  // Array example
  @Prop({ type: [BodySchema], default: [] })
  body: BodyContentInterface[];

  // Single example
  @Prop({ type: BodySchema })
  body: BodyContentInterface;
}
export const ChaptersSchema = SchemaFactory.createForClass(ChaptersApi);

This saves correctly and shows the timestamps when you have that option set on your schema
