How can I init Google Places Api key without AppDelegate, SwiftUI + GooglePlaces

Question

import SwiftUI
import GooglePlaces

struct Place: Identifiable {
    var id = UUID().uuidString
    let name: String
    let identifier: String
}

class GooglePlaceManager: ObservableObject {
    
    @Published var places: [Place] = []
    
    static let shared = GooglePlaceManager()
    
    private let client = GMSPlacesClient.shared()
    
    enum PlacesError: Error {
        case failedToFind
    }
    
    public func findPlaces(
        query: String) {
            let filter = GMSAutocompleteFilter()
            filter.type = .geocode
            client.findAutocompletePredictions(
                fromQuery: query,
                filter: filter,
                sessionToken: nil) {   (res, error) in
                    guard let res = res, error == nil
                    else {
                        return
                    }
                    
                    let places: [Place] = res.compactMap {
                        Place(name: $0.attributedFullText.string, identifier: $0.placeID)
                    }
                    self.places = places
                }
    }
}

@main
struct MyApp: App {
    var body: some Scene {
        WindowGroup {
            TestView()
                .onAppear {
                    GMSPlacesClient.provideAPIKey("API-Key")
                }
        }
    }
}

struct TestView: View {
    
    @StateObject var googlePlaceManager = GooglePlaceManager()
    @State var text = ""
    
    var body: some View {
        
        VStack{
            TextField("Search place ...", text: $text)
                .onChange(of: text, perform: { _ in
                    googlePlaceManager.findPlaces(query: text)
                })
            VStack {
                ScrollView {
                    ForEach(googlePlaceManager.places) { place in
                        Text(place.name)
                            .font(.body)
                            .foregroundColor(.blue)
                    }
                }
            }
            Spacer()
        }
    }
}

I tried onAppear, but it's not working.

Error: Terminating app due to uncaught exception 'GMSPlacesException', reason: 'Google Places SDK for iOS must be initialized via [GMSPlacesClient provideAPIKey:...] prior to use'

(But if it is possible to add AppDelegate to SwiftUI, you can also show it if it can solve the problem)
