Wait, but since the user didn't specify the exact app, some of this might be speculative. If Room-509 VR isn't a known app, I might be making things up. Need to be cautious. Maybe it's a hypothetical app, so I'll have to assume standard VR installation procedures. Alternatively, if it's a real app not widely known, the guide would be generic but still structured. I should mention that the steps are based on typical VR app setups and advise checking the official site for accurate info.
