How do I make my script generate text in an InputField?

I have a code that can generate a code in a Text.UI, but it does not generate that code in texts with InputField.

 public InputField input;
     public Text resultMarkupFormat;
 
     public Toggle bold;
     public Toggle italic;
 
     public Dropdown colorList;
 
     string[] boldFormat = new string[2] { "<b>", "</b>" };
     string[] italicFormat = new string[2] { "<i>", "</i>" };
 
     string[] hexadecimal = new string[31]
     {
     "No Color",
     "<color=#ff0000>Red</color> :#ff0000",
     "<color=#ffe100>Yellow</color> :#ffe100",
     "<color=#ff6600>Orange</color> :#ff6600",
     "<color=#77c2ff>OrangeRed</color> :#77c2ff",
     "<color=#ccff00>Lime</color> :#ccff00",
     "<color=#00ff00>Green</color> :#00ff00",
     "<color=#62ffab>Teal</color> :#62ffab",
     "<color=#00ffff>Cyan</color> :#00ffff",
     "<color=#1e90ff>Dodger Blue</color> :#1e90ff",
     "<color=#0000ff>Blue</color> :#0000ff",
     "<color=#5a00ff>Blue Violet</color> :#5a00ff",
     "<color=#9800ff>Violet</color> :#9800ff",
     "<color=#ff00ff>Pink</color> :#ff00ff",
     "<color=#ff0084>Deep Pink</color> :#ff0084",
     "<color=#ff7777>Light Red</color> :#ff7777",
     "<color=#ffce81>Light Orange</color> :#ff9c70",
     "<color=#ffef81>Light Yellow</color> :#fff070",
     "<color=#ffef81>Light Lime</color> :#e3ff62",
     "<color=#77ff79>Light Green</color> :#77ff79",
     "<color=#81ffb6>Light Teal</color> :#81ffb6",
     "<color=#adfcff>Light Cyan</color> :#adfcff",
     "<color=#87c8ff>Light Dodger Blue</color> :#87c8ff",
     "<color=#77c2ff>Light Blue</color> :#77c2ff",
     "<color=#a087ff>Light BlueViolet</color> :#a087ff",
     "<color=#bd87ff>Light Violet</color> :#bd87ff",
     "<color=#f287ff>Light Pink</color> :#f287ff",
     "<color=#ff78d1>Light Deep Pink</color> :#ff78d1",
     "<color=#FFFFFF>White</color> :#FFFFFF",
     "<color=#969696>Gray</color> :#969696",
     "<color=#000000>Black</color> :#000000",
     };
 
     void Start()
     {
         colorList.ClearOptions();
 
         for (int i = 0; i < hexadecimal.Length; i++)
         {
             string[] hexa = hexadecimal[i].Split(':');
             Dropdown.OptionData data = new Dropdown.OptionData();
             data.text = hexa[0];
             colorList.options.Add(data);
         }
 
     }
 
     void Update()
     {
         resultMarkupFormat.text = VerifyResult();
     }
 
     string VerifyResult()
     {
         string[] markup = new string[2] { "", "" };
 
         if (input.text.Length > 0)
         {
 
             markup[0] = bold.isOn ? boldFormat[0] : "";
             markup[0] += italic.isOn ? italicFormat[0] : "";
             if (colorList.value > 0)
             {
                 string[] hexa = hexadecimal[colorList.value].Split(':');
                 markup[0] += "<color=" + hexa[1] + ">";
             }
 
             markup[1] = bold.isOn ? boldFormat[1] : "";
             markup[1] += italic.isOn ? italicFormat[1] : "";
 
             if (colorList.value > 0)
                 markup[1] += "</color>";
 
         }
 
         return markup[0] + input.text + markup[1];
     }
