2D Tapping game popup problem

Hello! I'm trying to create a 2D tapping reflex type of game but got stuck when trying to generate a new circle to click on. So i have this button object with a picture of a circle in it which you can press and then a new button circle object is supposed to generate. The code I've written looks like this and a new button object is created but it gets created outside of the canvas and when you drag it into view it's just a transparent object which nothing happens with. What i want to do is create a new circle within a marked area inside my canvas everytime someone clicks on the object. Any help will do!

public class ButtonFunction : MonoBehaviour
{
public void SpawnCircle()
{
GameObject circleAppearing = GameObject.Find("ButtonsToClick");
Instantiate(circleAppearing);
Destroy(circleAppearing);
}
}

 

Remember the first rule of GameObject.Find():

Do not use GameObject.Find();

Apart from that, definitely start with some basic Unity tutorials for doing this sort of game.
