view.familyActivityPicker shows only categories. No apps or websites.

As can be seen here, all categories are expanded but nothing under them:

Not sure if related, but when I tried to upload my app for internal TestFlight testing I got following error:

The code looks like this:

    @ObservedObject var model : MyModel
    @State var isPresented = false
    var body: some View {
        Button("select apps to discourage"){
            isPresented = true
        }.onAppear {
            Task {
                do {
                    try await AuthorizationCenter.shared.requestAuthorization(for: .child)
                    
                } catch {
                    
                }
            }
            

        }.familyActivityPicker(isPresented: $isPresented, selection: $model.selectionToDiscourage)

    }

}

Now I am wondering, is there one more thing that I need to do before familyActivityPicker would work?

Here is what I have done: I subscribed to $99 Apple developer plan, Then I was finally able to see and add Family Controls capability under my Xcode project, Then I created Apple Family and logged in iphone (and simulator) as child. Then several days ago I submitted this form - https://developer.apple.com/contact/request/family-controls-distribution (not sure if this was mandatory for internal testing, but I have not received any communication from Apple - even confirmation for my request).
