How to use the cozy-client.QueryDefinition function in cozy-client

const ids = included.indexOf(':')
      ? included.map(x => x.split(':')[1])
      : included

    const docs = fromPairs(
      ids.map(id => {
        return [id, client.getDocumentFromState(assoc.doctype, id)]
      })
    )

    const missingIds = Object.keys(docs).filter(id => !docs[id])
    if (!missingIds || !missingIds.length) {
      return Object.values(docs)
    } else {
      return new QueryDefinition({ doctype: assoc.doctype, ids: missingIds })
    }
  }
}
