Change Sequelize default foreign key with through tables

I have two tables, apps and services. On services the PRIMARY KEY is set to field called orn. I created a through table between these two tables called apps_services with appId and serviceId

 appId: {
        type: Sequelize.UUID,
        references: {
          model: 'apps',
          key: 'id'
        }
      },

      serviceId: {
        type: Sequelize.STRING,
        references: {
          model: 'services',
          key: 'orn'
        }
      },

But here is a problem, when i use app.addService(foundService); (this creates a relationship between that app instance and foundService). When i used node debugger, i found out that sequelize tried inserting an id into serviceId instead of an orn

Executing (default): INSERT INTO "apps_services" ("id","appId","serviceId","createdAt","updatedAt") VALUES ('8d85f9b9-b472-4165-a345-657a0fe0d8ad','49f3daa4-1df4-4890-92f8-9a06f751ffb7','8cab340d-d11b-4e3b-842c-aeea9a28c368','2021-02-16 00:22:17.919 +00:00','2021-02-16 00:22:17.919 +00:00') RETURNING "id","appId","serviceId","userId","selfGranted","createdAt","updatedAt";

the third value in the bracket, the problem is id is not the foreignKey but orn is

below is the service table, we can see the orn column, which is the PRIMARY KEY and foreign key linking to the apps_services table.

Is there a way to force sequelize to use the orn field?

module.exports = (sequelize, DataTypes) => {
const apps_services = sequelize.define('apps_services', {
    id: {
        type: DataTypes.UUID,
        defaultValue: new DataTypes.UUIDV4(),
        unique: true,
        primaryKey: true
    },
    appId: {
        type: DataTypes.UUID,
    },

    serviceId: {
        type: DataTypes.STRING,
    },
    userId: {
        type: DataTypes.UUID
    },
    selfGranted: DataTypes.BOOLEAN
}, {
    timestamps: true
});

apps_services.associate = function (models) {
    models.apps.belongsToMany(models.services, {
        through: apps_services
    });

    models.services.belongsToMany(models.apps, {
        through: apps_services
    });
};
//apps_services.sync({alter: true});

return apps_services;

};

// this is apps_services migration

module.exports = {
up: async (queryInterface, Sequelize) => {
 await queryInterface.createTable('apps_services', {
   id:{
     type: Sequelize.UUID,
     defaultValue: new Sequelize.UUIDV4(),
     unique: true,
     primaryKey: true
 },
   appId: {
     type: Sequelize.UUID,
     references: {
       model: 'apps',
       key: 'id'
     }
   },

   serviceId: {
     type: Sequelize.STRING,
     references: {
       model: 'services',
       key: 'orn'
     }
   },

   userId: {
     type: Sequelize.UUID,
     references: {
       model: 'Users',
       key: 'id'
     }
   },

   createdAt: {
     allowNull: false,
     type: Sequelize.DATE
   },
   updatedAt: {
     allowNull: false,
     type: Sequelize.DATE
   },
   selfGranted: Sequelize.BOOLEAN,
 });
},

down: async (queryInterface, Sequelize) => {
 await queryInterface.dropTable('apps_services');
}
};

Below is the services table
