How to localize pattern description in SLES 15 SP3

Hello Team, In SLES 15 SP3, how are the patterns and package descriptions translated? Until SLES 12 SP5, we were modifying the package package-translations by merging the po files for a translated language and creating the package-translations-$lang.mo files In SLES 15 SP3, I tried to do the same, merging all po files for a translated language and creating the package-translations-$lang.mo files. Now in SLES 15 SP3 during installation, if I change the language I am not getting the translated description for the patterns. I would really appreciate it if you could help us understand how to localize our patterns and package descriptions. Regards, Gaurav.
