After installation almost every app should have a "portal" button. This button is an easy and streamlined way of entering the Applications after installation. However, one should be aware that it does not magically follow changes inside the application (for example: from http to https).
Every questions.yaml file should contain the following snippets to enable the portal button. Please be aware to change `"http"` to `"https"` in services.main.port.protocol if your application uses http instead of https when running using "NodePort".
