Notes

Works on dedicated servers. If the bot connects but messages aren't appearing, double-check that Message Content Intent is enabled on your bot's settings page.

The /rcon slash command requires the Administrator permission in Discord. If you set guildId, the command registers instantly on that server. Leave it blank to register globally, which can take up to an hour to propagate.
