Can't add Video to Zoom background (old computer)

[flora3z]

I can add image backgrounds to my Zoom meetings (have green paper on  my back wall & stand) but no option to add a video for my b/g (timer video during Toastmasters meeting).    All others seem to be able to do this.   I can share screen but not change my b/g while on the Zoom meeting.  Thank you.
