ios – NEVPNProtocolIPSec unavailible on Apple TV?

I am porting my VPN app to tvOS 17. In iOS the VPN connects efficiently, nonetheless in tvOS saveToPreferences returns error Code 1: Couldn’t save VPN Configurations: Lacking protocol or protocol has invalid kind

May you advise what’s the issue with my code?

 func toggleVPN() {
    let vpnManager = NEVPNManager.shared()

    vpnManager.loadFromPreferences { (error) in
      if let error = error {
        print("Couldn't load VPN Configurations: (error.localizedDescription)")
        return
      }

      if vpnManager.connection.standing == .related || vpnManager.connection.standing == .connecting {
        vpnManager.connection.stopVPNTunnel()
      } else {
        vpnManager.isEnabled = true
        vpnManager.isOnDemandEnabled = true
        vpnManager.localizedDescription = "tvpn"
        let p = NEVPNProtocolIPSec()
        p.authenticationMethod = .sharedSecret // or .certificates
        p.serverAddress = <REDACTED>
        p.username = "consumer"
        p.useExtendedAuthentication = true
        // Retrieve password and shared secret references from the keychain

        let secretData = <REDACTED>.information(utilizing: .utf8)!
        let passData = <REDACTED>.information(utilizing: .utf8)!
        p.sharedSecretReference = strive! VPNKeychain.persistentReferenceFor(service: "vpn", account: "SharedSecret", password: secretData) // I took this half from Apple dev boards, it is examined in iOS
        p.passwordReference = strive! VPNKeychain.persistentReferenceFor(service: "vpn", account: "Password", password: passData)

        vpnManager.protocolConfiguration = p
        vpnManager.saveToPreferences { (error) in
          if let error = error {
            print("Couldn't save VPN Configurations: (error.localizedDescription)")
            return
          }

          do {
            strive vpnManager.connection.startVPNTunnel()
          } catch {
            print("Couldn't begin VPN Connection: (error.localizedDescription)")
          }
        }
      }
    }
  }

persistentReferenceFor implementation will be discovered right here: https://developer.apple.com/boards/thread/84194?answerId=252309022#252309022

This code with none adjustments works on iOS

One other factor I seen, is that there is not any com.apple.developer.networking.vpn.api entitlement for tvOS 17, however NEVPNManager is obtainable there based on documentation.
