I'm trying to do something fairly similar to this but with face detection, can I ask what you're using to make this happen in Unity, and on WebGL no less? I can't find anything that seems to work without paid assets.

Hi, sorry for replaying now, it's been a while since we looked at the project. For hand detection we used Python script using a model called "Mediapipe" from Google. For Python-Unity communication we used shared memory. I didn't make the WebGL version, but the process is a bit more complex there from what I heard.
