Data key of the template fragment.

  body: {
    compositions: [{
      minTemplateAPIVersion: '1',
      layout: {
        type: CustomTemplateFragmentNames.text,
        dataKey: 'message',
      },
    }],
  },
}

const notificationOption: TemplateCustom = {
  //...
  templateOptions: myTemplate,
  templateData: {
    message: 'My Custom Notification Message',
  }
};
