AirPlay destination devices may need to be added to the Home in the Home.app (on iPad or iPhone), and be assigned to a room.

If your TV is not AirPlay-enabled, then you will need to connect a streaming device that can provide AirPlay receiving functionality. That can be an Apple TV set-top box, or select third party device.
AirPlay functionality is separate from the Apple TV app, although there is overlap for supported TVs. It depends on the exact model, though.
