The command management plugin lets you choose which channels commands can be used in, and disable whichever commands you like.
The channels assigned as command channels will be blacklisted.
Blacklisted command channels are channels in which commands will not work.
The channels assigned as command channels will be whitelisted.
Whitelisted command channels are the only channels where commands will work.
This is where you assign channels to be either blacklisted or whitelisted.
If you only want commands to be used in a channel designated for bots only, an idea would be to whitelist that channel.
This is where you disable specific commands for your server. Disabled commands may not be used by anyone.
