How to use the rrule.YEARLY function in rrule

const computeYearly = ({ mode, on, onThe }) => ({
  freq: RRule.YEARLY,
  ...(mode === 'on' ? computeYearlyOn(on) : computeYearlyOnThe(onThe)),
});

const doesRecurringEventsOverlap = (startingDate, endingDate, recurringRule) => {
    if (!recurringRule || !startingDate || !endingDate ||
        !('frequency' in recurringRule) || !('interval' in recurringRule)) return false;

    const freqMap = {
        YEARLY: RRule.YEARLY,
        MONTHLY: RRule.MONTHLY,
        WEEKLY: RRule.WEEKLY,
        DAILY: RRule.DAILY,
    };

    const dayMap = {
        MO: RRule.MO,
        TU: RRule.TU,
        WE: RRule.WE,
        TH: RRule.TH,
        FR: RRule.FR,
        SA: RRule.SA,
        SU: RRule.SU,
    };
