For your sample app to work, you should have a Kontent.ai project containing content. Your app should be then configured with its environment ID. You can either get it by signing in using your Kontent.ai credentials or by signing up for a trial. Later, it will be converted to a free plan.
You may wish to either select from existing projects or create a new sample project. The app will be configured with its environemt ID.
Alternatively, you can configure your app manually by submitting an environment ID below.
Alternatively, you may wish to use the shared project (environemt ID "975bf280-fd91-488c-994c-2f04416e5ee3").
Note: You cannot edit content in the shared project.
