VSAN option is not showing in vCenter webclient

Gents, Dell VxRail team has recently deployed VxRail 4.5 with vCenter appliance, psc, VxRail manager and VxRail log insight. My question is when I connect vCenter through web client I don't see VSAN option under configure tab. There is only DRS and HA option available. Not Sure if it doesn't show in VxRail environment or there is some gap , if fixed will start showing VSAN in vCenter. Please suggest?
