occ:preview:generate-all not supported

[theking2]

I read here https://apps.nextcloud.com/apps/previewgenerator there should be a preview:generate-all command but on my setup it is failing/mising

  [Symfony\Component\Console\Exception\CommandNotFoundException]  
  Command "preview:generate-all" is not defined.                  
                                                                  
  Did you mean one of these?                                      
      notification:generate                                       
      preview:cleanup                                             
      preview:generate                                            
      preview:reset-rendered-texts   

is this a docmentation issue? NC 33.0.2
