Just look for it in the notification bar where you can find the quick buttons for wifi and data, airplane mode etc, press it or hold press it then it will automatically create a folder.
T.N. you can't find it if you're using a launcher, you should use the default launcher first before proceeding
Me too I can't find it, even the knox & vpn. Why A12 don't have built in / pre installed apps like knox, secure folder, vpn, samsung pass ? Unlike my J8 it's there already.
