I had one of these with a new account recently. I forget what platform it was, but it wasn't anything from Meta. Didn't need to move your face in any specific way, but it was obviously doing some checks for signs of life so a simple photo wouldn't work. I found a video of some random dude on YouTube just staring at the camera, and I pointed my camera my computer screen while that played. Difficult, considering they only allowed the front-facing camera to work.
