Both links install the same bot and slash commands. Administrator is simplest. Required permissions is narrower and includes the current permission set used by moderation, tickets, Deep Work threads, generated files, verification, and temporary invites.
Simplest setup
Administrator
Best when you want moderation, tickets, verification, backups, raid protection, GrandJam, and Jambot administrator tools to work without manually adjusting individual permissions.
Uses the current Jambot permission bitfield. It includes Create Instant Invite for one-use admin invites, plus the thread and attachment permissions GrandJam needs for Deep Work and generated files.
