Need help zooming out on my camera

[Tunes4toons]

I use several virtual meeting platforms and use the same webcam for all platforms. Whenever I am using Zoom, my video appears that I am closer to the camera, showing just my head and shoulders. When I am using Teams or WebEx, the same camera shows my head and upper torso. 
Because many of my colleagues are Deaf, I use sign language to communicate, but I have to back up my chair every time I want to sign something so they can see my signs. My camera only shows this close up view when using Zoom. 
Is there a way a can manually manipulate the camera to zoom out, so I appear farther from my camera? I'm using a basic Logi webcam. Not sure if the make of the camera matters since this only happens when we are on Zoom.

You will need to use software to control the zooming. https://techsynchron.com/how-to-zoom-out-logitech-webcam/
