How to populate (join) tables in Nestjs + mysql

I have one to many relationship. What I'm trying to do is when I call Group all query. I want in devices keys have all POPULATED devices. How should I set my models ?

I have 2 models

1. Group

    import Device from "src/device/device.model";
   
    interface GroupCreateAttrs {
        name: string,
        desctiption: string
    }
   
    @Table({tableName: "groups"})
    export default class Group extends Model<Group, GroupCreateAttrs> {
    @Column({ type: DataType.INTEGER, autoIncrement: true, unique: true, primaryKey: true})
    id: number
   
    @Column({type: DataType.STRING, unique: true, allowNull: false})
    name: string
   
    @Column({type: DataType.STRING, defaultValue: ""}) 
    description: string
   
    @HasMany(() => Device)
    devices: Device[]
   

   }

2. Device

     import Group from "../ groups/group.model"
   
   
   
   interface DeviceCreationAttrs {
        model: string
    }
   
    @Table({tableName: "devices"})
    export default class Device extends Model<Device, DeviceCreationAttrs> {
   
    @Column({type: DataType.INTEGER, unique: true, autoIncrement: true, primaryKey: true})
    id: number;
   
    @Column({type: DataType.STRING, unique: true, allowNull: false})
    model: string;
   
    @ForeignKey(() => Group)
    @Column({type: DataType.INTEGER, allowNull: true, defaultValue: null})
    groupId: number
   
    @BelongsTo(() => Group)
    group: Group
   

   }

What I'm ideally trying to do is when in service of group I make a call as

@Injectable()
export default class GroupService {
    constructor(@InjectModel(Group) private groupRepository: typeof Group) {}

    async getAll() {
        const all = await this.groupRepository.findAll()
        return all
    }
}

I should receive array of groups WHERE every object has a keys name, description AND populated devices as ->

[{"id" : 1,
 "name": "Tablets",
 "description": "Elect devices",
 "devices": [{ "id" : 1, "name":"Ipad"}]
}]
