You have to have the Oculus app open then launch SteamVR, the Oculus app just handles encoding to send to the headset once you launch SteamVR it functions normally and all SteamVR games will work with it. There are very few games that are specially configured to launch directly in the Oculus app which can be annoying if you are trying to use an overlay, but it doesn't actually change anything about playing the game itself. I've only played 2 games where I have no choice to launch in SteamVR and those are Poker Stars and Everyday Golf, it's not a limitation of the headset it's just dev laziness to not add an option.
If you use Virtual Desktop to stream over wifi then that handles the encoding and you don't need the Oculus app at all.
