Is ContactAccessButton broken?

Simple question - on iOS 26 ContactAccessButton does not appear to show any UI when attempting to search for a contact in either the contact access picker on the ContactAccessButton.

This behavior occurs in the Apple provided sample code , as well as a basic example:

struct ContentView: View {
    
    @State var searchText : String = ""
    
    var body: some View {
        VStack {
            
            TextField("Search", text: $searchText)
            
            ContactAccessButton(
              queryString: searchText,
              ignoredEmails: nil,
              ignoredPhoneNumbers: nil,
              approvalCallback: { identifiers in
                print(identifiers)
            })
        }
        .padding()
    }
}

Am I doing something wrong or is this just not working?
