How to convert *.zoom video files to mp4?

Hello everybody! Need some help with my Zoom video converting. Today I recorded a meeting on my computer (locally), 2 files with the extension *.zoom were formed. One takes up 1.2 GB, the second - 8 MB. Usually I double-click on one of these files and everything is converted to mp4. But in this case, nothing happens. I tried to transfer everything to another computer and try to convert the video there - no changes. What should I do? Thanks for support.
