Running Ubuntu with Podman

I knew this had replaced “egon” with the username(vidya) I wanted to create but I repeat that the command:
chmod -R vidya:users /home/vidya
is giving this error
chmod: invalid mode: ‘vidya:users’
Try ‘chmod --help’ for more information.

The error shows that it is taking ‘vidya:users’ as a mode and there may be syntax problem here.
Incidentally username vidya is not the same as username on Endless OS but I think this should not matter.
