I saved data on workbook on following code

export const storeSettingsToWorkbook = async (settingsType: Settings, storeData: 
 WorkbookModel) => {
  return Excel.run(async (context) => {
const originalXml = createXmlObject(storeData);
const customXmlPart = context.workbook.customXmlParts.add(originalXml);
customXmlPart.load("id");
await context.sync();

// Store the XML part's ID in a setting
const settings = context.workbook.settings;
settings.add(settingsTitles[settingsType], customXmlPart.id);
await context.sync();
 })
}

when i get data -it works normally.But when i want to get this data form another "add-in" on Excel- I cannot get this data

      const {settings} = context.workbook;
  const sheet = context.workbook.worksheets.getActiveWorksheet().load("items");
  const xmlPartIDSetting = settings.getItemOrNullObject(settingsTitles[settingsType]).load("value");

  await context.sync();


  if (xmlPartIDSetting.value) {
    const customXmlPart = context.workbook.customXmlParts.getItem(xmlPartIDSetting.value);
    const xmlBlob = customXmlPart.getXml();
    await context.sync()


    const parsedObject = parseFromXmlString(xmlBlob.value);
    const normalizedData = normalizeParsedData(parsedObject);

Any ideas?
