Is there a way to enable "Services" menu for an application? Almost every OSx Application has a service menú like this:



But I've found that my HipChat for MAC doesn't have. I don't know if there is a setting that will enable this menu or it is something related to the way the application was created.
It has to do with the way the application is created. More about Services in Apple Developer Documentation.

I suggest you direct HipChat Devs to this page.
