Match strings from an array to fire specific UnityEvents?

Question

I am trying to find/create a system that will allow different things to happen on a single object at different times. That's a simplification but its the basic idea.

I want to be able to compare strings and fire specific Unity Events when the string matches.

I have looked at generic Unity events and creating a type so I can have an array of strings and events but the array isn't even showing up in the inspector for me to start testing.

Here is the pseudo code I have started with: using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.Events;

 public class ObjectEventString
 {
     public string cardType;
     public UnityEvent objectEvents;
 
     public ObjectEventString()
     {
 
     }
 }
 
 public class ObjectInteractionController : MonoBehaviour
 {
     //This aray is not showing up in the inspector?
     public ObjectEventString[] variations = new ObjectEventString[2]; 
 
     void Start()
     {
         
     }
 
     public void ObjectEventAction()
     {
         // for each matching string from the ObjectEventString class cardType and the server cardType trigger an event.
 
         //Something like:
         //check the string in the inspector against strings being passed by the server
 /*         foreach(string cardID in variations)
         {
             //when the string matches 
             if(variations.cardType == server cardType from server)
             //play the desired events and ignore the others.
                 cardID.variations.objectEvents.Invoke();
         } */
     }   
 }

Thank you.

This does what I want

         private string owningType = "";
         [Tooltip("String Array this interactable could apply to")]
         public string[] interactionType;
         [Tooltip("Array of events that will fire when matched at index with a string from above array upon interaction from player")]
         public UnityEvent[] interactableInteractedWithEvent;
         [Tooltip("Default event fired upon interaction from player")]
         public UnityEvent defaultInteractedWithEvent;
 
 
         void Start()
         {
             //left start so I can disable the script in the inspector.   
         }
 
         public void CheckForInteractedEvent()
         {
             Debug.Log("CHECK FOR INTERACTED EVENT");
             // loop through the strings of cardTypes i.e. "criticalComputerUpdate"
             for (int i = 0; i < cardType.Length; i++)
             {
                 // if it matches get the index and pass that index into the array of events to fire the event we tied to it
                 if(owningType == cardType[i])
                 {
                     Debug.Log("Fire the associated INTERACTED Event!");
                     interactableInteractedWithEvent[i].Invoke();
                 }
                 else
                 {
                     // do default...
                     defaultInteractedWithEvent.Invoke();
                 }
             }
         }
 
         public void CheckForInteractedCompletedEvent()
         {
             Debug.Log("CHECK FOR INTERACTED COMPLETED EVENT");
             defaultInteractedWithEvent.Invoke();
             owningType = "";
 
         }

Make a dictionary. The Key is a string, the Value is an Action

Sorry newb here, I have not used dictionary's and while I have been looking at them the past few days I don't understand how the Value can be a UnityEvent that I can set in the inspector to do different things at different times. I would like to put this script on as many as 150 objects in a scene and each object could have between 1 and 6 different events that can happen based on the string that is compared. can the dictionary populate an array of unity events in the inspector?
