Console.WriteLine($"Final value: {edited}");

using JRead;

var options = new JReadOptions

    AutoCompleteItems = new List<string> { "admin", "user", "guest" },
    AutoCompleteMinLength = 2,          // Show suggestions after 2 chars
    AddReturnedValueToHistory = false,  // Don't save passwords to history
    EscapingReturnsTheOriginalInput = false // ESC returns null
};
