Zoom on FireTV Cube

Since July 29, 2021 there's been an official Zoom client for the FireTV Cube product from Amazon, however I can find very little info on it.  If you click on the "More" button from the Zoom dashboard, one of the choices is "Camera Control".  Grayed out  in that menu is +/- magnifier and direction buttons to ostensibly control camera pan and zoom.  Below that is a toggle for mirroring the camera.  The only option active for me it the mirror toggle.   I'm using a Logitech C930e webcam with it, not exactly an obscure camera, but also not one of the four recommended in Amazon's announcement at the end of July.  Since I plan on placing the camera atop my big screen TV and the camera has a particularly wide angle lens (for a boardroom conference table) it's not very usable from my sofa. 

The four recommended cameras were the Logitech C920, the C922x, the C310, and the Wansview 101JD.  My questions is - does anyone have experience using the Zoom app on the Cube with one of these cameras, and does the zoom/pan controls work with it?  I would buy one of them if I knew the zoom/pan controls worked in the Zoom app.  TIA.
