The .desktop file for that YaST module (which is what makes it appear in the YaST control center) is /usr/share/applications/YaST2/org.opensuse.yast.OnlineUpdate.desktop which belongs to package yast2-online-update-frontend. On my x86_64 TW VM I have that package installed, but I don't see it in the y2logs of this openQA test case. It did install yast2-online-update, though: y2log-1.gz:2020-10-21 23:41:19 <1> ip-10-0-2-15(3087) [zypp::exec++] ExternalProgram.cc(start_program):260 Executing[C] 'rpm' '--root' '/mnt' '--dbpath' '/var/lib/rpm' '-U' '--percent' '--noglob' '--force' '--nodeps' '--' '/mnt/var/cache/zypp/packages/openSUSE-20201021-0/noarch/yast2-online-update-4.2.2-1.3.noarch.rpm' But there is no mention at all of yast2-online-update-frontend in those y2logs.
