how to draw path

I succeeded in drawing the line. However, it did not show a curve and did not implement path movement.

 public class DrawLine : ObjectBase
 {
     [Header("Line")]
     public GameObject linePrefab;
 
     [Header("Line Pooling Size")]
     public int poolingSize;
 
     private bool isDrawingStart;
     private Vector2 original$$anonymous$$ousePos;
     private Vector2 current$$anonymous$$ousePos;
 
 
     private List<GameObject> line_List = new List<GameObject>();
     private LineRenderer currentDrawingLineRenderer;
 
     protected override IEnumerator OnAwakeCoroutine()
     {
         return base.OnAwakeCoroutine();
     }
 
     private void Update()
     {
         if (Input.Get$$anonymous$$ouseButtonDown(0)) OnClick_DrawStart();
 
         if (Input.Get$$anonymous$$ouseButton(0) && isDrawingStart) Drawing();
 
         if (Input.Get$$anonymous$$ouseButtonUp(0)) OnClick_DrawEnd();
     }
 
     private void CreateLine()
     {
         if(line_List.Count < poolingSize)
         {
             GameObject temp = Instantiate(linePrefab);
             SetLineRendererPosition(temp);
             line_List.Add(temp);
         }
         else
         {
             SetLineRendererPosition(line_List[0]);
             ObjectPooling$$anonymous$$anager.$$anonymous$$oveFirstToEnd(line_List);
         }
     }
 
     private void SetLineRendererPosition(GameObject line)
     {
         currentDrawingLineRenderer = line.GetComponent<LineRenderer>();
         currentDrawingLineRenderer.SetPosition(0, original$$anonymous$$ousePos);
         currentDrawingLineRenderer.SetPosition(1, original$$anonymous$$ousePos);       
     }
 
     private void Drawing()
     {
         current$$anonymous$$ousePos = Camera.main.ScreenToWorldPoint(Input.mousePosition);
         currentDrawingLineRenderer.SetPosition(1, current$$anonymous$$ousePos);
     }
 
     #region Event
 
     private void OnClick_DrawStart()
     {
         isDrawingStart = true;
         original$$anonymous$$ousePos = Camera.main.ScreenToWorldPoint(Input.mousePosition);
         CreateLine();
     }
 
     private void OnClick_DrawEnd()
     {
         isDrawingStart = false;
     }
 
     #endregion Event
 }
