How to debug `podman unshare` commands / Podman permission issues?

I understand that podman unshare can be used to properly set the permissions on unprivileged containers. So podman unshare chown 1234:1234 -R /home/user/volume can be used to set the volume to the properly mapped ids.

But I'm getting permission errors when I'm trying to do that:

podman unshare chown -R 1234:1234 -R /home/user/foo/bar;  echo $?
chown: changing ownership of '/home/user/foo/bar': Operation not permitted
1

The first thing I thought about was directory permissions but it fails even if I'm giving the destination directory 0777. I'm calling the command as user user and the parent directories have these permissions:

drwxr-xr-x root /home
drwxr-x--- user /home/user
drwxrwxrwx user /home/user/foo
drwxrwxrwx user /home/user/foo/bar

It isn't my intention to really use 0777 in production but something is off even with 0777 and it's not clear to me how to debug this.
