java – A number of subcommands in the identical command

I’m making an attempt to make a command that has a number of youngsters that every do a unique factor.
To visualise what I’m making an attempt to do, this is a picture:

I’ve tried to make use of literal("foo") after which a number of .then()
nevertheless it finally ends up like /foo subfoo1 subfoo2 subfoo3 and I’ve additionally tried to duplicate the setExecution() however it’s already outlined.

Here is my code:

import com.mer08.sidaland.sidaland.widespread.command.BaseCommand;
import com.mer08.sidaland.sidaland.core.config.configuracionsidacoins;
import com.mojang.brigadier.Command;
import com.mojang.brigadier.builder.LiteralArgumentBuilder;

import internet.minecraft.command.CommandSource;
import internet.minecraft.command.Instructions;
import internet.minecraft.entity.participant.ServerPlayerEntity;
import internet.minecraft.util.Util;
import internet.minecraft.util.textual content.StringTextComponent;

public class ExampleCommand extends BaseCommand {

    public ExampleCommand(String identify, int permissionLevel, boolean enabled) {
        tremendous(identify, permissionLevel, enabled);
    }
    @Override
    public LiteralArgumentBuilder<CommandSource> setExecution() {
        return builder.executes(supply -> execute(supply.getSource())).then();
    }

    non-public int execute(CommandSource supply) {
        if(supply.getEntity() instanceof ServerPlayerEntity) {
            supply.getEntity().sendMessage(new StringTextComponent(""), Util.DUMMY_UUID);
        }
        return Command.SINGLE_SUCCESS;
    }
}

And right here is the BaseCommand class

import com.mojang.brigadier.builder.LiteralArgumentBuilder;

import internet.minecraft.command.CommandSource;
import internet.minecraft.command.Instructions;

public class BaseCommand {
    protected LiteralArgumentBuilder<CommandSource> builder;
    boolean enabled;

    public BaseCommand(String identify, int permissionLevel, boolean enabled) {
        this.builder = Instructions.literal(identify).requires(supply -> supply.hasPermissionLevel(permissionLevel));
        this.enabled = enabled;
    }

    public LiteralArgumentBuilder<CommandSource> getBuilder() {
        return builder;
    }

    public boolean isEnabled() {
        return enabled;
    }

    public LiteralArgumentBuilder<CommandSource> setExecution() {
        return null;
    }
}
