Hello CAPatterson,
Welcome to post here. Angelique's way is correct. @Angelique, thanks for your sharing.
To blur the background in the video meeting, try to click More options > Blur my background.
You can get the details from here.
Please be noted that not all devices support background, and our related teams are working on it. If Blur my background appears in the menu, which means you're in business. Meanwhile, Linus users aren't able to use it at this time. Hope you can understand this limitation.
Have a wonderful time.
Regards,
Rudy
