How to run function in another script with prefabs? C#

Question

I have gameObject A with script A, how do I then call a function in gameobject b's script b without using the "direct reference" made in the Editor by dragging the gameobject with scriptb onto the "other" variable?

Reason being is that script A's gameobject needs to be a prefab as it will be instantiated and when needed with run a function in scriptb which is my gamecontroller

 using UnityEngine;
 public class ScriptA : MonoBehaviour
 {
   public ScriptB other;
  
   void Update()
   {
     other.DoSomething();
   }
 }

 using UnityEngine;
 public class ScriptB : MonoBehaviour
 {
   public void DoSomething()
   {
      Debug.Log("Hi there");
   }
 }

I've tried all sorts such as the below but just can't get my head around it.

 ScriptB otherScript = GetComponent<ScriptB>();
 otherScript.DoSomething();
 
 ScriptB other = (ScriptB) go.GetComponent(typeof(ScriptB));
 other.DoSomething();

If I have scriptA and scriptb on the same gameobject it just works but putting them on different gameobjects only works using the "direct reference" made in the Editor.

Brilliant I got it working.

 public NameoftheScript other;
 public GameObject SpawnZone;
 
 void Awake ()
     {
         // Setting up the reference.
         GameObject SpawnZone = GameObject.Find("NameoftheGameObject");     
         other = SpawnZone.GetComponent<NameoftheScript >();                 
                     
     }
 
 //just use the below where ever to activate
 other.NameoftheFunction();

If you can get GameObject.Find working, then you should be able to combine it with your GetComponent example to get what you want:

ScriptB otherScript = GameObject.Find("Name of GameObject with ScriptB you want").GetComponent(); otherScript.DoSomething();
