image moving randomly after clicking it

So, for my class I have to remake my prototype of my app which is a whack-a-mole style game, and I'm trying to figure out how to make the image of the coin that I'm using as the mole to move in random places after you click it.

Like in applab/codelab ⇓

I'm having trouble doing the same thing in Figma and tried looking it up to see if I could find an answer but haven’t found a single helpful answer. I've figured out the timer and score except for the coin. 

So, I would love for some tips or directions on how to do it.
