Making a custom manager class

Before you can add a subcommand, you need to have a central manager that collects all subcommmands Create a new class and let it extend either extends CommandManager or TabCompletionCommandManager. The difference is that TabCompletionCommandManager subcommands are visible when typing them in the chat. Create a new, empty constructor.

public class ExampleManager extends TabCompletionCommandManager {

    public ExampleManager() {

    }
}

If you want to make custom logic for the onTabComplete() & onCommand() methods, which are required to work, override them to apply that code to my code.
