Virtual background

[lj18]

Hi

I have just started studying at university and due to the pandemic all our lectures are viaZoom. We've been asked to download Zoom via the student section of our university website due to encryption issues. However I cant activate a virtual background. I have a MacBook air with macOS BigSur with a processor of 1,6Ghz Dual core intel core i5. 

How do I get virtual background to work??
