Installing foreman_openscap plugin failing

I have tried the workaround provided here: [Enabling ansible plugin results in failure of db:migrate - #5 by dafsjr], but I am not winning

I executed the ff commands:
mv /opt/theforeman/tfm/root/usr/share/gems/gems/foreman_openscap-5.2.1/app/graphql /tmp

Unfortunately I could not find the register.rb file:

[root@foreman foreman_openscap]# ls -ltr /opt/theforeman/tfm/root/usr/share/gems/gems/foreman_openscap-5.2.1/lib/foreman_openscap/
total 40

I could only find the graphql code bolded in the contents of the engine.rb file below:
