React Native App with implemented Carplay doesnt show content on carplay screen if IPhone App is terminated

Question

Apps like Spotify, Tidal etc show content if the phone apps are terminated and i click on the App Icon in Carplay Simulator. My App doesnt so, it shows an empty screen. If the phone app is in background or active, everything is working well. I have no idea what i am doing wrong. Please help! Thanks in advance!

Some code:

import Foundation
import CarPlay
class SceneDelegateCarPlay: UIResponder, CPTemplateApplicationSceneDelegate {
...
func templateApplicationScene(_ templateApplicationScene: CPTemplateApplicationScene, didConnect interfaceController: CPInterfaceController) {
    print("SceneDelegateCarPlay.templateApplicationScene(), didConnect")
    // start render content
    ...
}

"templateApplicationScene is called and render content when:

1. Carplay App is closed & Iphone App is active or in background -> Click on Carplay App Icon
2. Carplay App is open (no content visible) & Iphone App is terminated -> Start Iphone App

I wonder how i can render content outside of a case like these
