Blur Background

[dwn3543]

Trying to blur my background using Mac OS and can't find any place to change the setting. I've had it before but no longer. I have updated my computer and have the following:

Intel(R) Core(TM) i5-8257U CPU @ 1.40GHz. Supposedly, there should be the option, but nothing in sight. 

Thanks!

Can anyone help figure out the problem please?
