[Pharo-dev] Committed to wrong repo in sthub , any way to delete my commit ?

Hi , I was working on my project Hyperion and I made a mistake. I committed my latest commit to PharoLauncher repo instead of my Hyperion repo in smalltalkhub. Is there a way to delete the commit so that my Hyperion package does not appear inside the PharoLauncher repo ? Sorry for the mistake :(
