I was looking into a pending edit request for [this question](https://stackoverflow.com/questions/39823657/playing-random-pairs-of-words-in-sound-arrays), and I was too quick to click "approve".  

Is there a way to retract that "approval"?  

Or do I have to wait for the system to detect that I am the only approver, and that everybody else disagrees and that I need to be banned from reviewing for X amount of time?
