How do I join two entities linked with 1-1 relationship and add the joined entity on a particular property of the first entity?

Question

I have 2 entities with a one to one relationship between them created with typeorm.

 @ObjectType()
    @Entity()
    export class Interaction extends BaseEntity {
      @Field()
      @PrimaryGeneratedColumn()
      id!: number;
    
  
      @Field(() => AF_Metadata)
      @JoinColumn()
      @OneToOne(() => AF_Metadata, { eager: true })
      metadata: AF_Metadata;
    }
    }



 @ObjectType()
    @Entity()
    export class AF_Metadata extends BaseEntity {
      @Field()
      @PrimaryGeneratedColumn()
      id!: number;
    
      //Relationships
      @OneToOne(() => Interaction, { onDelete: "CASCADE" })
      interaction: Interaction;
    
    
    }

How do I join these entities by adding the AF_Metadata entity to the metadata property in the Interaction entity. I am able to add the whole AF_Metadata object to the interaction but not to the metadata propery. This is my sql query so far.

select * from interaction int
left join af_metadata metadata on int."metadataId" = metadata.id
order by int."createdAt" DESC

Current result:

{
    id: 8327,
    metadataId: 1,
}

Desired result:

{
id: 8327,
metadata: {
metadataId: 1
}
}
