"Click" a GUI Button using only joystick input

So the game I am currently making uses only joystick input, which i am finding out Unity GUI doesn't support at all, I figured out how to cycle the focus through my menu after a massive search.

what i am on now, and my question, is how to either "click" or activate what is in focus through GUI.FocusControl(), or alternatively move the cursor to a specified position and simulate a mouse click with a joystick button.

i hope someone knows how to do this or i'm going to have to create my own buttons which would be as crude as it gets.

here's the current code.

 public GUISkin mySkin;
  
  
  private int focus = 2;
  public float delay = .5f;
  private bool isCheckingJoy = false;
  private string[] menuOption = new string[3];
  
  void Start(){
  menuOption[2] = "Play";
  menuOption[1] = "Options";
  menuOption[0] = "Exit";
  }
 
  void OnGUI(){
  GUI.skin = mySkin;
  Rect myRect = new Rect(10,10,100,20);
  GUI.SetNextControlName("Play");
  GUI.Button(myRect,"Play");
  
  myRect = new Rect(10,30,100,20);
  GUI.SetNextControlName("Options");
  GUI.Button(myRect,"Options");
  
  myRect = new Rect(10,50,100,20);
  GUI.SetNextControlName("Exit");
  GUI.Button(myRect,"Exit");
  
  GUI.FocusControl(menuOption[focus]);
  }
  
  
  
  void SetFocus(int change){
  if(change == 1){
  focus ++;
  if(focus == 3){
  focus = 0;
  }
  }else if(change == -1){
  focus --;
  if(focus == -1){
  focus = 2;
  }
  } 
  }
  
  void CheckJoy(){
  if(Input.GetAxis("PlayerOne_Vertical") > .1f){
  SetFocus(1);
  }
  if(Input.GetAxis("PlayerOne_Vertical") < -.1f){
  SetFocus(-1);
  }
  }
  
  void Update(){
  if(Mathf.Abs(Input.GetAxis("PlayerOne_Vertical")) == 1 && !isCheckingJoy){
  CheckJoy();
  isCheckingJoy = true;
  Invoke("Delay",delay);
  }
  
  if(Input.GetButtonUp("PlayerOne_LightAttack")){
  }
  }
  
  void Delay(){
  isCheckingJoy = false; 
  }
