How to detect Double Clicking Horizontal/Vertical Axis on joystick

Hello everybody! I'm trying to write a control character for the fighting game and I need to detect double click on the joystick Axis. I have a script for detecting the arrow buttons but I do not understand how to adapt it for the joystick. Anybody knows how to do this?

public class InputCore : MonoBehaviour {

 public static InputCore Global;

 public float MaxDoubleClickTime = 0.3f;

 float TimerA;
 float TimerD;
 
 public bool DoubleClickA;
 public bool DoubleClickD;

 void Awake () {
     Global = this;
 }
 

 void Update () {

     DoubleClickA = false;
     DoubleClickD = false;
     
     TimerA += Time.deltaTime;
     TimerD += Time.deltaTime;
     
     //A -----------------------------------------------
     
     if (Input.GetKeyDown (KeyCode.A))
     {
             if (TimerA <= MaxDoubleClickTime)
         {
             DoubleClickA = true;
         }
         
         TimerA = 0;
     }

     //D -----------------------------------------------
     
     if (Input.GetKeyDown (KeyCode.D))
     {
         
         if (TimerD <= MaxDoubleClickTime)
         {
             DoubleClickD = true;
         }
         
         TimerD = 0;
     }
 }

}
