Ios swift – Block (shield) a category of apps using ManagedSettings

I’m trying to block the entire "social" category using ManagedSettings. However, the function blockApps does not work because of a compiler error on the let socialCategory = AcitivityCategoryToken line (the compiler errors are "(Argument type ‘(UnboundedRange_) -> ()’ does not conform to expected type ‘Decoder’)" and "Missing argument label ‘from:’ in call").

The code is the exact same as the WWDC 2022 (this video) (at minute 5:30) but it still does not work.

import FamilyControls
import ManagedSettings

extension ManagedSettingsStore.Name {
    static let social = Self("social")
}

public class ScreenTimeApiModule: Module {
    public func definition() -> ModuleDefinition {
        Name("ScreenTimeApi")
        
        Function("blockApps") {
            let socialCategory = ActivityCategoryToken(...) //ERROR "(Argument type '(UnboundedRange_) -> ()' does not conform to expected type 'Decoder')" and "Missing argument label 'from:' in call"
            let socialStore = ManagedSettingsStore(named: .social)
            socialStore.shield.applicationCategories = .specific([socialCategory])
            print("Successfully blocked apps")
        }
    }
}
