Virtual Joystick for Drag Indicator

So I'm going to try to explain my issue, i'm making a mobile game based on golf, I made a Drag Indicator to show where you are aiming at, the problem is that when I aiming, I can't see where I'm aiming because my finger is covering up the drag line, so I thought it could be a good idea to make a Virtual Joystick that shows you a direction line, i made a kind of sketch to make it more visual. And I don't know how to do it, I know it's quite difficult to write it but I hope someone can help me, I'm giving this image to clarify all
