           description: 'Interval in which the announcement can be sent earlier than the configured `beforeExpiry`. The actual point in time when the announcement will be sent is `beforeExpire` plus a randomly chosen time within the `randomizationInterval`. E.g assuming `beforeExpiry` is set to 5m and `randomizationInterval` is set to 1m, the announcements will be sent between 5 and 6 minutes before the subject expires. If omitted, the default value will be applied. If set to minimum, no randomization will be applied.'
