Howto extend root partition on Oracle Linux 9 as kvm Guest

I create an Oracle Linux 9.4 as a kvm Guest initially with 40G virtual hard disk
After a while I needed to increase the disk size to 60G so I did it with qemu-img resize /media/kvm/storage1/oracle-9.4 +20G. However I was not able to resize the root partion inside Oracle Linux. After some trying I end up with this

I would like to have all 58GB in the / mount point
