Anti Spam Checking Function - Email Spam Scoring - Spam Assassin Configuration - Issue

Hi Team,

 As our adobe campaign application(on-premise) servers working under RHEL, we followed the steps from the following link for our lower environment servers.

https://experienceleague.adobe.com/docs/campaign-classic/using/installing-campaign-classic/additional-configurations/configuring-spamassassin.html?lang=en#installation-steps-in-rhel-centos

cpan Digest::SHA1

cpan HTML::Parser

cpan Net::DNS

cpan Mail::SPF

cpan XML::LibXML

cpan XML::Writer

cpan Mail::SpamAssassin

After implementing the above steps, changes are not reflected under the adobe campaign client console level. It says "EMAIL SPAM SCORING -  The function is not configured" under Anti Spam score section of any email delivery(preview > more > anti spam checking).

Is there any steps further we need to do apart from the steps mentioned from the link?

Looking forward to see some solution on it.
