How to use the contentful/dist/contentful.browser.min.createClient function in contentful

export type SavedData = {
  entries: CmsEntry[],
  assets: Asset[],
  syncToken: string,
  updated: boolean
};

type SyncOpts = {
  initial: boolean,
  nextSyncToken?: string
};
type Client = {
  sync: SyncOpts => Promise
};

const client: Client = createClient({
  space: Config.CONTENTFUL_SPACE_ID,
  accessToken: Config.CONTENTFUL_API_KEY
});

export const getCmsData = async (
  loadCmsDataFn: typeof loadCmsData = loadCmsData,
  updateCmsDataFn: typeof updateCmsData = updateCmsData
): Promise => {
  const localCmsData = await loadCmsDataFn();
  const hasLocalCmsData = !!localCmsData;

  if (hasLocalCmsData) {
    return { ...localCmsData, updated: false };
  }

  return updateCmsDataFn();

};
type SyncOpts = {
  initial: boolean,
  nextSyncToken?: string
};
type Client = {
  sync: SyncOpts => Promise
};

type UpdateEvents = () => Promise;
type GetEvents = (
  loadEvents?: loadEvents,
  updateEvents?: updateEvents
) => Promise;

const client: Client = createClient({
  space: Config.CONTENTFUL_SPACE_ID,
  accessToken: Config.CONTENTFUL_API_KEY
});

export const getEvents: GetEvents = async (
  loadEventsFn = loadEvents,
  updateEventsFn = updateEvents
) => {
  const localEventsData = await loadEventsFn();
  const hasLocalEventsData =
    !!localEventsData && localEventsData.events.length > 0;

  if (hasLocalEventsData) {
    return localEventsData.events;
  }
