iMovie Project File Missing

After working on a slo-mo video on iMovies through my iPhone, i exported the file and wasn't able to find it. On videos or even within the iMovie app. I tried connecting my phone to the Mac and couldn't find the file yet. tried the same with a few other video files and ended up missing those video files too. I did look into iCloud. But was unable to find it.

Looking for support here. Thank you in advance.
