Scheduled posts API on Mastodon seems a bit rough.
1. Post payload is a bit different than published posts (ScheduledStatus https://docs.joinmastodon.org/entities/ScheduledStatus/#example vs Status https://docs.joinmastodon.org/entities/Status/#example)
2. There's API to reschedule & delete but no edit https://docs.joinmastodon.org/methods/scheduled_statuses/
Looking back at the initial PR (https://github.com/mastodon/mastodon/pull/9706): "The scheduled date must be at least 5 minutes into the future. At most, 300 toots can be scheduled at the same time. Only 50 toots can be scheduled for any given day."
