Configure the Experiences System
!xp announce set #TextChannel
!xp announce set #🏆-rank
If you want to put the message in the same channel where the level was won, instead of indicating a channel just give
!xp announce set same
!xp announce disable
!xp announce enable
This command allows you to see which channel has been defined for level up messages and see if it is enabled or disabled as well as for the Experiences System.
