Not able to run Jio 5G under iOS 16.5 IPhone 13 Pro

I am not able to use Jio 5G eSIM under iOS 16.5 IPhone 13 Pro. The Jio says that one has to active mobile data - Voice & Data - 5G ON - Standalone but the Standalone option is not visible in my iPhone 13 Pro.

But at the same time if I am using physical Jio SIM I am able to see Standalone and my jio 5G services run fine.

so I feel that Apple needs to provide an update for IPhone user having eSIM.
