A "feature" that I don't want

I recently bought a Macbook Air and just had a Zoom meeting on it for the first time. My computer told me it had turned on this feature where when I move my head, the camera automatically centers my head in the video frame. It didn't give me the option of rejecting or turning off this feature. I don't like it. I've already forgotten the name of this feature. Can anyone here tell me what it's called and how to turn if off?
