Screen Records in FaceTime

So a month ago, I screen recorded a Facetime call i had with my sister on my old iphone 11 when i told her some big news and wanted to get her reaction. i even took facetime photos. i ended the screen recording and the red thing popped up saying it was saved to photos. i was still talking with her, so i didn't bother checking. earlier this week, i had screen recorded a very important facetime call on my new iphone 12, which i backed up my 11 to, while I was quarantined and was unable to attend the meeting. i ended the recording and the notification telling me it was saved popped up. when i went to go look for the screen recording from a month ago, it wasn't there. then i realized the screen recording from earlier this week wasn't either. does anyone know where i can find these videos at? i've tried looking everywhere in photos and nothing.
