Bone follow

I need bone1 to follow a certain point how to do it ?
Bone1 is a child of bone2.

This should probably work if not please tell me!

    using UnityEngine;
    using System.Collections;
    
    public class BoneMovement : MonoBehaviour
    {
        public Transform bone1;
        
        //The Target Position.
        public Transform target;
    
        // Speed In Units Per Second.
        public float speed;

        void Start()
        {
            //gets the bones transform
            bone1 = GetComponent<Transform>();
        }
        void Update()
        {
            bone1.position = Vector3.MoveTowards(bone1.position, target, speed*Time.deltatime);
        }
    }

That’s what i used

C#

 x1 = RightHand.transform.localPosition.z * -1;
        x2 = RightHandMove.transform.localPosition.z * -1;
        float x3 = RightHandMove.transform.localPosition.z * -1;

        y1 = RightHand.transform.localPosition.y * -1;
        y2 = (RightHandMove.transform.localPosition.y * -1) + (float)0.0061083;
        float y3 = RightHand.transform.localPosition.y * -1;

        float c1start = Mathf.Pow((x2 - x1),2) + Mathf.Pow((y2 - y1), 2);
        float b1start = Mathf.Pow((x3 - x1),2) + Mathf.Pow((y3 - y1), 2);

        c1 = Mathf.Sqrt(c1start);
        b1 = Mathf.Sqrt(b1start);

            float A = (Mathf.Acos(b1 / c1)) * (float)57.295779513082320876798154814105;

        if (y2 > 0 && x2 >0)
        {
            Bone8.transform.localRotation = Quaternion.Euler((A + 90) * -1, 0, 0);
        }
        else if (y2 < 0 && x2 < 0)
        {
            Bone8.transform.localRotation = Quaternion.Euler((A - 90) * -1, 0, 0);
        }

        else if (y2 > 0 && x2 < 0)
        {
            Bone8.transform.localRotation = Quaternion.Euler(A + 90, 0, 0);
        }
        else if (y2 < 0 && x2 > 0)
        {
            Bone8.transform.localRotation = Quaternion.Euler(A - 90, 0, 0);
        }
