We should avoid await constructions like this. await keywords should appear at the start of a statement, or at the start of the right-hand side of an assignment. await is a very powerful keyword and we should always aim to make it very clear where it appears, instead of sneaking it into declarations like this.

const connectionPromise = (async () => {
  const actualizedCalendarQuery = await calendarQueryPromise;
  return {
    ...defaultConnectionInfo(viewer.platform ?? 'web', viewer.timeZone),
    actualizedCalendarQuery,
  };
})();
