Dell CSI Driver Isilon

I'm using this on OpenShift 4.6.6. Earlier I was running driver version v.1.3.0 for last six months and suddenly it got broken. The v1.3.0 has option to create storage-class and snapshot-class while installing the driver.

Since my driver broken, i had to install new version v.1.6.0. The PODs are running, but there is no storage-class. How to create storage-class with allowVolumeExpansion: true ?
