Thanks for the help.

SharePoint pages can now be shown after adding Web-App SSO elements, which is the information inside "webApplicationInfo".

As my custom app will only contain provider-hosted pages, I have created some SharePoint Pages for the redirection to those Provider-hosted pages instead of directly using the URL.
