VR - display second window

Hi guys!

I want to have a second window for another camera. No input or anything from that window.
When i hit play, i want the VR first person camera window to show up as usual, but i want a second window where i want to have a second camera rendering another angel of the player.

How can i achieve this?

I have tried using this plugin

But when i hit the PlayScene button, it shows a window but its black.
