How to Add Virtual Background During Meetings?

[Angela29]

When I clicked on Settings and scrolled to Virtual Background, I was able to add and save 2 additional Background Images, but I can't figure out how to add them to my background during meetings (despite reading articles and watching YouTube videos). I started a test meeting and clicked on the lower left 'Stop Video' and clicked on 'Virtual Image'. All I saw was 'NONE' with a black image and 'BLUR.' There were no other options. I would appreciate someone helping me with this issue. Thank you!
