Schedule settings expect a cron like format, where the first value is minute, second is hour and third is day of the week.
Examples:
0 15 *: Run task every day at 15:00 in the afternoon.
30 8 */2: Run task every second day of the week (Sun, Tue, Thu, Sat) at 08:30 in the morning.
auto: Sensible default.
Note:
Avoid an unnecessary frequent schedule to not get blocked by YouTube. For that reason, the scheduler doesn't support schedules that trigger more than once per hour.
