getDisplaySetFromSeries(series, study, dicomWebClient, authorizationHeaders) {
    const instance = series.getFirstInstance();

    return {
      plugin: 'pdf',
      modality: 'DOC',
      displaySetInstanceUid: utils.guid(),
      wadoRoot: study.getData().wadoRoot,
      wadoUri: instance.getData().wadouri,
      sopInstanceUid: instance.getSOPInstanceUID(),
      seriesInstanceUid: series.getSeriesInstanceUID(),
      studyInstanceUid: study.getStudyInstanceUID(),
      authorizationHeaders: authorizationHeaders,
    };
  },
};

const create = useCallback(props => {
    const { id } = props;

    let dialogId = id;
    if (!dialogId) {
      dialogId = utils.guid();
    }

    setDialogs(dialogs => [...dialogs, { ...props, id: dialogId }]);

    return dialogId;
  }, []);
