How to change the layout during Zoom livestreaming ?

[Pat77]

Dear all, does anyone know how to change the layout during Zoom livestreaming?  When I am sharing screen, in speaker view, the webcam/speaker thumbnail is very small on top right hand corner.  Can I change the size of the webcam/speaker thumbnail?  Or move it to lower right hand corner?  Thanks very much.

@Pat77 Unfortunately, the output format of the video stream is fixed at this time, so those images cannot be changed or moved.
