Which (Network) Targets Does The Orchestrator iOS App Talk To?

Which (network) targets does the app talks to that can be important for the configuration? Does the app only talk to the specific Orchestrator URL? Or does is maybe also talk to other specific URLs like https://orchestrator-url/oauth/xyz/ or something to fetch the relevant data for showing in the app?

The mobile app should only need the one Orchestrator URL to get all the relevant data it needs.
