We listen for the success message each bump service posts in the channel — Disboard's 'Bump done!', Discadia's confirmation, etc. The cooldown timer starts from that exact moment, not from when you ran the command.
Will it spam my members?
No. BumpReminder sends one reminder per cooldown, only when the bump is actually ready — not random chatter in the background.
What permissions does the bot need?
Read Messages, Read Message History, Send Messages, Embed Links, and Mention Roles in the reminder channel (so your own message can include @role if you add it). We don't ask for admin permissions.
