When building an app, is it possible or restrict or prohibit all network access for the app at the permission level? I am using React Native with hundreds of npm modules, and I want to ensure there is no data leakage from my app. It does not need internet access, so I would like to shut down all access, period.

I am new to CloudKit - and my test on the Mac (Swift, M1, Monterey, XCode 14 Beta 4) which creates records appears to be working. However, when I log into the CloudKit Console, using the same account as the iCloud account my Mac is logged into, no containers appear. I have tried this several times over 2 days, and no containers appear in the console. The container I am using appears in iCloud storage (via System Preferences > iCloud > Manage), so it appears to be there on iCloud. Am I doing something wrong? What I want to do is query the data, which, I understand, you must use the Console to make it queryable. (It would be nice to be able to do this programmatically, but haven't found a way yet). Thank you.
