        return [{
            event: 'md.batchAdd.before',
            functional: this.mdBatchAddBefore.bind(this)
        }]
    }
  // If this is a middleware plugin in a vcrm project, swap the interaction parameter positions
   // mdBatchAddBefore(plugin, context)
  	mdBatchAddBefore(context, plugin) {
		return new Promise((resolve, reject) => {
         resolve();// if you want to intercept the add action, call reject()
      })
   }
}

Notes

1. This hook is triggered before object selection, so no new data has been generated yet
