Align game object base on 2 point

Questions & Answers
1

Maybe this is a dump question, but I just start in Unity, sorry.

I have 2 point on the world, both of them have position ( a vector3).
Between them is a LineRenderer. LineRenderer only need 2 point to be draw on world.

lr.SetPosition(0, vector3_0);
lr.SetPosition(1, vector3_1);

I want to change the LineRender with a cube (or any game object).
My try so far:

//Test SampleCub
sampleCube.transform.position = lr.transform.position;
sampleCube.transform.rotation = Quaternion.LookRotation(vector3_0-vector3_1);

Not working. Please help. Thanks

using UnityEngine;
using System.Collections;

    public class LinePoints : MonoBehaviour
    {
        //set the number of points you your line to have in order
        public GameObject[] Points;
    
        private LineRenderer line;
    
        private void Start()
        {
            //Make sure you have a LineRenderer component attached to an empty gameobject
            line = GetComponent<LineRenderer>();
        }
        private void Update()
        {
            for (int i = 0; i < Points.Length; i++)
            {
                //Sets Points
                line.SetPosition(i, Points*.transform.position);*

}
}
}
Here is a script I wrote that should work for you.
LineRenderers work by setting their positions in code by accessing their component

You want to aling the position of a point with a position of an object so when you move an object the point will move aswell?
If it is that then this code might help:
In this case we will change second point

public GameObject object;
 Vector3 point1; 
Vector3 point2; 
Vector3 objectPos; 
Transform tr = object.GetComponent<Transform>();
 void update() { 
point2 = tr.position;

lr.SetPosition(0,point1); 
lr.SetPosition(1, point2);
 }
