How to move spam to "Junk / SPAM" Folder automatically?

Hi. I have spamassassin installed. The e-mails are marked as [*** SPAM ***] but end up in the inbox. How do I make a rule to move to a Dedicated folder ? eg “Junk” or “SPAM”

I use this tutorial Filtering Spam in RainLoop, AutoReply and Email Filters with Sieve - #2 by Master3395 - Blog Posts - CyberPanel Community
but i have Imgur: The magic of the Internet

As you can see in the picture, I am not able to enter the filters
