I've been playing some live chess bullet and blitz games. When I'm short on time i enter a premove. I wonder if there is any way to undo that premove?

The situation is this: I have just a few seconds left, i enter a premove. My opponent has more time and he is thinking. When he is thinking I found a better move and I wanted to play that one instead of my entered premove. How can I undo the premove and play the better move? If I undo the premove before he plays his move it's not a take back situation.

Can someone enlighten me? Thank you.

make a right click and the pre-move will be undone!

thank you. I'll try it next time.
