In this example commands are processed using config.mode:
https://www.spantree.net/blog/2017/06/26/scala-native-for-cli-tools.html

  parser.parse(args, Config()) match {
    case Some(config) =>
      config.mode match {
        case "choose" =>
          Picker.choose(config.objects, config.count).foreach(println)
        case "roll" =>
          println(Picker.roll(config.objects(0).toInt, config.objects(1).toInt))
      }

    case None =>
    // arguments are bad, error message will have been displayed
  }

However mode is not a method of Config.
Which is the correct way of processing .cmd subcommands? Almost all examples just show

// do something

A more complete example would be very helpful.

I understood how it works:

.action((_, c) => c.copy(mode = "update"))

So issue is closed for me
