Can I Export the Summary Photomontage Movie From a Memory In Photos?

Photos creates short movies of ‘moments’ or events: and some of them are beautiful, with carefully chosen soundtracks.
I would like to be able to save and share these movies, but I can’t see how to do it. I can share the pictures of the event, but not the movie.
Am I missing something?
Thanks for your attention to this.
I want to export the movie ‘summary’ of a ‘moment’ in Photos.
This is so that I can share it with people who don’t have Macs.
I can share the photos from the ‘moment’, but this movie seems to be generated only within Photos.
