JsonUtility serialize custom getter setter field

Question

So how do i get the id to be included in JSON when i call JsonUtility.ToJson(CharacterData) ?

 [Serializable]
 public struct CharacterData  {
     private string _id;
 
     [SerializeField]
     public string id {
         get {
             if(_id == null || _id == "") {
                 Guid g = Guid.NewGuid();
                 string GuidString = Convert.ToBase64String(g.ToByteArray());
                 GuidString = GuidString.Replace("=","");
                 GuidString = GuidString.Replace("+","");
                 _id = GuidString;
             }
             return _id;
         }
         set {
             _id = value;
         }
     }
 }

AFAIK you don't. You need a public backing field that actually gets serialized and deserialized. So something like

 public string _id;
 public string id { get {return whatever-you-want} set { _id = whatever-you-want; } }

But I can't guarantee this is right. I only know I've been doing this for the past year or so and am pretty confident I researched it back then or otherwise wouldn't be doing it.
