How to use the results of a dice roll?

Question

Lots of tutorials on how to make a dice script. Very few on how to use dice results to do something. I'm wondering how in this script I get the RollTheDice method to "publish" the finalSide result so that I can use it? Or how do I get a method to look inside RollTheDice and find finalSide? I've been stuck on this for days now. Trying different things. I'm too new to programming to really understand.

 using System.Collections;
 using UnityEngine;
 
 public class Dice : MonoBehaviour {
 
    
     private Sprite[] diceSides;
 
   
     private SpriteRenderer rend;
 
     
     private void Start () {
 
    
         rend = GetComponent<SpriteRenderer>();
 
      
         diceSides = Resources.LoadAll<Sprite>("DiceSides/");
     }
     
   
     private void OnMouseDown()
     {
         StartCoroutine("RollTheDice");
     }
 
     // Coroutine that rolls the dice
     private IEnumerator RollTheDice()
     {
      
         int randomDiceSide = 0;
 
       
         int finalSide = 0;
 
        
         for (int i = 0; i <= 20; i++)
         {
            
             randomDiceSide = Random.Range(0, 5);
 
            
             rend.sprite = diceSides[randomDiceSide];
 
             yield return new WaitForSeconds(0.05f);
         }
 
       
         finalSide = randomDiceSide + 1;
 
   
         Debug.Log(finalSide);
     }
 }

Here's an example that adds a function to call at the end. @rallyall

  using System.Collections;
  using UnityEngine;
  
  public class Dice : MonoBehaviour
  {
 
      private Sprite[] diceSides;
      private SpriteRenderer rend;
      
      private void Start ()
      {
          rend = GetComponent<SpriteRenderer>();
          diceSides = Resources.LoadAll<Sprite>("DiceSides/");
      }
      
    
      private void OnMouseDown()
      {
          StartCoroutine("RollTheDice");
      }
  
      // Coroutine that rolls the dice
      private IEnumerator RollTheDice()
      {
          int randomDiceSide = 0;
          int finalSide = 0;
 
          for (int i = 0; i <= 20; i++)
          {
              randomDiceSide = Random.Range(0, 5);
              rend.sprite = diceSides[randomDiceSide];
              yield return new WaitForSeconds(0.05f);
          }
          finalSide = randomDiceSide + 1;
          Debug.Log(finalSide);
          DiceComplete(finalSide);
          yield return null;
 
      }
      
      private void DiceComplete(int dieRoll)
      {
         //Do whatever you want with the dieRoll here
      }
  }

I also found this works:

Within the RollTheDice method add:

//name of script using this roll//.diceSideThrown//or whatever you want to call it// = randomDiceSide + 1;

Then in the script that's using it add outside of any method:

public static int diceSideThrown //or the name you gave it// = 0;

try removing randomDiceSide = 0; because you are setting the variable on the coroutine but the coroutine doesn't stop so it sets it to 0 every 0.05 seconds if im wrong im sorry im kinda new to cs

or you can debug.log inside the coroutine but then you gotta stop the coroutine after the log
