How to rename an iCloud container?

I have created an iCloud container for my iOS app in Signing & Capabilities section of TARGETS named iCloud.myApp
I have many problems with iCloud and I found in one tutorial that:

The app’s bundle ID and iCloud containers must match and they must exist in the developer account. For example, if the bundle identifier is com.myDomain.myApp, then the iCloud container name should be iCloud. plus the bundle bundle id: iCloud.com.myDomain.myApp.



So the question is how and where to change it from iCloud.myApp  to iCloud.com.myDomain.myApp?
Containers in Signing & Capabilities are not editable. I cannot find it in CloudKitDashboard as well. Or should I create a new container?
