Yearly billing should be an option but I can only set up to 6 month intervals max. I'm also unable to set anything other than 1, 3, 6 for days, weeks, months.
As per the comment in shared/payloads/stripe/StripePriceRecurringPayload.ts
@param interval_count number Optional. The number of intervals between subscription billings. For example, interval=month and interval_count=3 bills every 3 months. Maximum of one year interval allowed (1 year, 12 months, or 52 weeks).
