        return "weather";
    }

    @Override
    public String getOptionName() {
        return "city";
    }

    @Override
    public void handle(CommandAutoCompleteInteractionEvent event) {
        String input = event.getFocusedOption().getValue();
        List<String> cities = findCitiesMatching(input);

        List<Command.Choice> choices = cities.stream()
            .limit(25)
            .map(city -> new Command.Choice(city, city))
            .toList();

        event.replyChoices(choices).queue();
