如何判断在使用System.CommandLine时是否指定了选项？

using System.CommandLine;
using System.CommandLine.Parsing;

public static class CommandLineParser
{
    public static bool IsOptionSpecified(Option option, ParseResult parseResult)
    {
        return parseResult.HasOption(option);
    }

    public static bool IsOptionSpecified(string optionName, ParseResult parseResult)
    {
        return parseResult.HasOption(optionName);
    }
}

public class Program
{
    public static void Main(string[] args)
    {
        var option = new Option<string>("--output");
        var parseResult = new Parser().Parse(args);
        
        bool isOutputOptionSpecified = CommandLineParser.IsOptionSpecified(option, parseResult);
        Console.WriteLine("Is --output option specified? " + isOutputOptionSpecified);
    }
}
