   I think you will find Ubuntu installs it by default. It is just disabled   
   in the default configuration of grub.   
      
   Here on a fresh install of 22.04 *Server* they even install it:   
      
   apt-cache policy os-prober   
   os-prober:   
     Installed: 1.79ubuntu2   
     Candidate: 1.79ubuntu2   
     Version table:   
    *** 1.79ubuntu2 500   
           500 http://us.archive.ubuntu.com/ubuntu jammy/main amd64 Packages   
           100 /var/lib/dpkg/status
