Presenting Paywall on every n launches

I want to present the Paywall, if needed, on every 4th launch of the app. I can track the launch count, but can’t seem to figure out how to couple this with .presentPaywallIfNeeded in the ContentView.
 

// Show paywall every 4th launch
        if launchCount % 4 == 0 {
            // Present RevenueCat Paywall
            presentPaywall()
        }

import Foundation
import RevenueCat

class SubscriptionManager: ObservableObject {
    @Published var hasPro: Bool = false

    init() {
        checkSubscriptionStatus()
    }

    func checkSubscriptionStatus() {
        Purchases.shared.getCustomerInfo { (customerInfo, error) in
            if let error = error {
                print("Error fetching customer info: \(error.localizedDescription)")
                return
            }

           print("checkSubscriptionStatus")

            DispatchQueue.main.async {
                self.hasPro = customerInfo?.entitlementsn"pro"]?.isActive == true
                print("hasPro: \(self.hasPro))")
            }
        }
    }
}
