how to call a method from another script?,Does not contain a definition for and no accessible extension method accepting a first argument errors

I have looked almost 10 different topics but nothing worked for me.

I have such code

updateScore.cs

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 using UnityEngine.UI;
 public class updateScoreText : MonoBehaviour
 {
     Text scoreText;
     // Start is called before the first frame update
     void Start()
     {
         scoreText = GetComponent<Text>();
     }
 
     // Update is called once per frame
     void Update()
     {
         
     }
     public void scoreUpdate(int score)
     {
         scoreText.text = "Score: " + score;
     }
 }
 

I want to call scoreUpdate method in another script

I tried

public updateScore addScoreText; addScoreText = GameObject.Find("Text").GetComponent().scoreUpdate(points);

in another script

but it shows error error CS1061: 'updateScore' does not contain a definition for 'scoreUpdate' and no accessible extension method 'scoreUpdate' accepting a first argument of type 'updateScore' could be found (are you missing a using directive or an assembly reference?)

,This is my full error : error CS1061: 'updateScore' does not contain a definition for 'scoreUpdate' and no accessible extension method 'scoreUpdate' accepting a first argument of type 'updateScore' could be found (are you missing a using directive or an assembly reference?)

I have two different scripts

PlayerPoint.cs

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 using UnityEngine.UI;
 public class playerPoint : MonoBehaviour
 {
     public int points = 0;
     float timers = 0.0f;
     public int seconds = 0;
     bool scoreUpdated = false;
     public updateScore addScoreText;
     // Start is called before the first frame update
     void Start()
     {
         InvokeRepeating("addPoint",5.0f,5.0f);
     }
 
     // Update is called once per frame
     void Update()
     {
 
     }
     void addPoint()
     {
         if (scoreUpdated == false)
         {
             points += 5;
             addScoreText.scoreUpdate(points);
         }
     }
 }
 

updateScore.cs

   using System.Collections;  
   using System.Collections.Generic;
   using UnityEngine;
   using UnityEngine.UI;
   public class updateScoreText : MonoBehaviour
 {
     Text scoreText;
     // Start is called before the first frame update
     void Start()
     {
         scoreText = GetComponent<Text>();
     }
 
     // Update is called once per frame
     void Update()
     {
         
     }
     public void scoreUpdate(int score)
     {
         scoreText.text = "Score: " + score;
     }
 }
 

Please could someone help me why I get this error when I already have scoreUpdate method in updateScore.cs file?
