This is interesting. In 2021, Shonen JUMP did a reality TV show in Japan which was a contest where they paired aspiring and talented manga artists with senior Shonen JUMP editors and had them compete to see who could produce the best manga. The winner got serialized and a Netflix sponsored anime of their work.
You can see the show here with English subtitles if you turn on the captions. (One note- the playlist is reverse order for some reason.)
