Custom enumeration class accessible through inspector?

Hi! I am working on my custom enumeration class, I think it looks beautiful and most of all in my opinion it's a good OOP solution. Any ideas how could I make its values (sword, exampleValue, troll) public CustomEnumeration dropDownList; accessible through inspector?

 using System.Collections.Generic;
 using System.Collections.ObjectModel;
 
 //Example
 public class CustomEnumeration
 {
     //Attribute
     public readonly Vector3 Position;
     public readonly string Word;
 
     //Easy foreach imitation
     protected static readonly List<CustomEnumeration> _enumeration = new List<CustomEnumeration>();
     public static ReadOnlyCollection<CustomEnumeration> Enumeration
     {
         get
         {
             return _enumeration.AsReadOnly();
         }
     }
 
     //"Enums"
     public static readonly CustomEnumeration sword = new CustomEnumeration(new Vector3(0,0,0), "Sw0rd");
     public static readonly CustomEnumeration exampleValue = new CustomEnumeration(new Vector3(1, 2, 3), "example");
     public static readonly CustomEnumeration troll = new CustomEnumeration(new Vector3(3, 2, 1), "troll");
 
     //PROTECTED constructor - only here (in this script) we can create enum values
     protected CustomEnumeration(Vector3 position, string word)
     {
         this.Position = position;
         this.Word = word;
         _enumeration.Add(this);
     }
 
     public void DoSth()
     {
         //Instead of switch statements we can expand our enumeration class by creating methods
         //So OOP
         //Wow
         //Such CleanCode
         //Doge is dead meme like Harambe
     }
 }
