Yeah, that never happened.
Remember that 47 minutes of video Israel was screening for reporters but did not release? They've gotten permission from some of the families and have released part of it. You definitely see people being killed on camera.
And the really important part isn't the video itself, but that it's stuff that Hams people chose to post on social media. Something to be cheered, not a horror.
And, no, they didn't get permission from any of the other victims families to publish on that site.
So, the IDF literally has no direct confirmation of rape.
