/**
 * Gravity Perks // Notification Scheduler // Trigger Twilio Feed
 * https://gravitywiz.com/documentation/gravity-forms-notification-scheduler/
 *
 * Use a scheduled notification to trigger a Twilio feed instead.
 *
 * Instruction Video: https://www.loom.com/share/58faeab7b4884ccbb177fa3e30c9587e
 *
 * Instructions:
 *
 *  1. Setup your Twilio feed.
 *      a. In the "Name" setting of your Twilio feed include the following string "twilio.FID@notificationscheduler.com".
 *      b. Replace "FID" with your Twilio feed's ID. You can find this in the URL via the "fid" parameter.
 *  2. Setup your scheduled notification.
 *      a. Set the "Send To Email" to the same string you included in your Twilio feed's name (e.g.
 *          "twilio.FID@notificationscheduler.com" with the FID replaced with your actual FID).
 *      b. Configure your desired schedule with Notification Scheduler's "Schedule" setting.
 *      c. The notification has other required fields. Fill them out however you wish. They will not be used.
 *
 * When the scheduled notification is sent, the actual email will be aborted and the Twilio feed will be sent instead.
