Would it be possible to support Chroma Keying for MR headsets via Virtual Desktop

Is your feature request related to a problem? Please describe.
No

Describe the solution you'd like
Virtual Desktop allows you to use chroma keying (defining a color that should be replaced) to enable passthrough in PCVR applications and games. I use this in Shapelabs for example and it works surprisingly seamless. This video shows it off pretty well:

Describe alternatives you've considered
N/A

Additional context
Not sure if such a feature would be possible globally and I understand that it won't make sense for all type of UE games (I want it for Pinball FX btw).
