Any way to know when a video was deleted from my channel?

All the videos on the channel were privated and then put back to public 2 weeks later, but some were missing. I know that they were deleted during those 2 weeks but don't know the exact day. One of my managers had deleted them but they are denying it so I want to know at least the exact day of deletion.

YT support didn't provide me with any useful info apart from saying that the videos cannot be recovered.
Are there any tricks that I can use to find the deletion date if I have the URL of the video?

Check your email.

if those videos uploaded as private and never changed to public, there will be no trace of them on google cache or other indexes

You will receive an email immediately.

I didn't get any notifications of deletion, nor do I remember YT ever sending those out. Just tried on one of my channels and there was no email notification of deletion.

They were public then made private for the duration of around 2-3 weeks. Some of them got deleted while private.
