Quest + Link & remote desktop only show my pc screen, not the VR scene in the headset

When in Oculus Link Remote Desktop and I press play in Unity, I assumed that it would start to play in the Oculus Quest headset, but it only shows like a window on my desktop.

I use Unity 2019.3.15 and XR Plugin 1.3.4, latest update on Oculus.
What am I missing here?

It should start the scene in VR, but it does not.
Any help is very appreciated.
