SwiftUI view does not update when FetchRequest data changes from inside Action Extension

I'm sharing a Core Data store with my action extension, which adds data to it. My app has a SwiftUI view that presents this data, fetched with a FetchRequest:

private struct VideosScrollView: View {

    @Environment(\.managedObjectContext) private var viewContext

    private var fetchRequest: FetchRequest<Video>

    init(sortOrder: String, tagIds: String, showWatched: Bool) {
        fetchRequest = Video.getFetchRequest(sortingBy: "addDate",
                                             with: sortOrder,
                                             showWatched: showWatched,
                                             tagIds: tagIds)
    }

    var body: some View {
        ScrollView {
            if fetchRequest.wrappedValue.isEmpty {
                ContentEmptyView()
            } else {
                ForEach(fetchRequest.wrappedValue) { item in
                    VideoCellView(video: item)
                }
            }
        }
    }
}

After adding data from the action extension and going back to the app, the view is not updated. Only after CloudKit finished a sync is that the view notices something changed and updates itself.

How can I force my SwiftUI view to update when data changes in the action extension?
