Restoring an edited recording

I wanted to trim the last three minutes of a Zoom cloud recording. I thought I was supposed to mark the part of the recording to “Trim”, instead I only have remaining those 3 minutes that I didn’t want. I looked for guidance and could only find advice that I was supposed to return to the video and click on “restore”  there is no such option. I have now lost the entire recording except for the part i don’t want! How do i get it back?
