'GameObject' does not contain a definition for 'Find' [Assembly-CSharp]csharp(CS0117)

Hi! I am new to unity and would like to add 4 virtural buttons to move my player game object (up,down,left,right) but I am met with this problem: 'GameObject' does not contain a definition for 'Find' [Assembly-CSharp]csharp(CS0117).

Does anyone perhaps know how I can fix this? I have unity 2020.3.3f1 & my code so far looks like this. It's basically nothing

using UnityEngine; using Vuforia;

public class ButtonEventHandler : MonoBehaviour { public GameObject vbs; void Start() {
vbs = GameObject.Find("btn1"); / vbs.GetComponent().RegisterOnButtonPressed(OnButtonPressed); vbs.GetComponent().RegisterOnButtonReleased(OnButtonReleased); / }

 void OnButtonPressed(VirtualButtonBehaviour vb){
     switch(vb.VirtualButtonName){
         case "btn1": //rechts
                 Debug.Log("right");
             break;
         case "btn2": //oben
                 Debug.Log("up");
             break;
         case "btn3": //unten
                 Debug.Log("down");
             break;
         case "btn4": //links
                 Debug.Log("left");
             break;
     }
 }

 void OnButtonReleased(VirtualButtonBehaviour vb){
     
 }

}
