Zoom green screen work-around?

Can anyone point me to a green screen work-around for Zoom so that I video conference without sharing more home decorating than I want to :->

Zoom or any jpeg provides a suitable background but without a green screen it’s pretty useless.

Your thoughts welcome.

Thx

Here is a Youtube video about this subject, maybe helpful…

Thanks -
found that the white walls in my basement do the trick. BTW, the monthly cost of zoom seem very high but so it goes. They get to make money, too.
