There’s also a command-specific list, where you can make customized permissions for each command.
By default, these are all synced to the command permission at the top.
You can unsync an individual command to make further customizations.
Command permissions work similarly to channel permissions: making changes at the top level will affect everything that’s synced within it. Selecting an individual command will bring up the command-specific toggles, where you can see whether they’re synced or not at the top, and make any necessary changes.
