Feature Request: Can I record overlay video with transparent background with OBS?

Hey guys, I have the following hardware / software setup:
  1. Windows 10 20H2 64-bit
  2. OBS 26.0.2
  3. nVidia GeForce RTX 2080
  4. AMD Ryzen 3900x
  5. 32GB DDR4 RAM
Camera Setup
  1. Elgato green screen
  2. Elgato Camlink 4k
  3. Panasonic Lumix G85 (4k30)
Question

I would like to record myself in front of my green screen as a transparent video. Later on, I could use this transparent video as an overlay to record another video.

In other words, I would like to create a scene, with a single source (Camlink 4k), that uses the Chroma Key filter. The scene background should be transparent. The final result would be a video of me that's overlayed on top of a transparent background.

I've tried creating an OBS scene, but the background is black. I can't find any options to make the scene background transparent.

Is it possible to accomplish this?

Experience Level

FYI I've been using OBS regularly for about a year. I'd rate my skills 7 / 10, so pretty familiar, but maybe I'm just missing an obvious option.
