How to start the VR app in VR mode from Unity IDE in Horizon Workrooms?

I am trying to use Horizon Workrooms as developer environment for VR development. I can edit scene and source code in Horizon Workrooms. But when I start the app in Unity IDE, it starts in flatscreen mode instead of VR mode. PC Oculus Home runs VR apps from Unity IDE in VR mode, but it cannot track Logitech K830 keyboard,

Is it possible using Horizon Workrooms to start the VR app from Unity IDE in VR mode?
