Installing ksh on UBI8 minimal image

Hi All,
We want to execute ksh shell scripts in a container based off UBI8 minimal image. How to install ksh and where I can get the required rpms?
Could not find any rpms at:https://cdn-ubi.redhat.com/content/public/ubi/dist/ubi8/8/x86_64/baseos/os/Packages/k/

Thanks for the pointers.
