IOS 15, Wallet and office keys

It has been some time since WWDC and first beta and couldn't find any information about iOS 15 new features to integrate office keys into Wallet. Is this feature live in iOS 15.0 or is it coming later this year?

We are highly interested in this feature to offer access control features to our customers but it seems there are no information about Wallet improvements mentioned on WWDC 10092
