Is the user required to remember the name of my app in order to interact with it via Siri AI?
This will depend on the user's usage patterns. Initially, they might need to mention your app name in case there are other apps on device that conform to the same App Schemas. Over time, the system will learn that the user performs certain actions with certain apps, and will know to route to the correct app automatically.
