iOS On Demand Resource with MAUI

Question

With Asset packs for Android now in MAUI .NET 9, I wonder how to use the iOS equivalent of On Demand Resources in MAUI. I thought I could port over a few of my older Apps (which still use Xamarin.Forms) to MAUI but those app are using On Demand Resources for iOS to download ressources only when needed. However, neither the Build Action BundleResource nor the On Demand Resource Tags can be set in a MAUI project. So how is it supposed to be set to work for iOS and Android?
