[CentOS] polkit-gnome-0.106 with CentOS 7.5 ???

What can anyone tell me about the polkit-gnome package that came with 
CentOS 7.5? Looking at the Fedora pack for the same, it seems like I'm 
missing pieces of this package.

I start my gui session with startx instead of GDM. I am having a lot of 
authentication issues at the moment. I am somewhat familiar with dealing 
with polkit but mostly things are not working well at all.

On an older version of openSUSE I once used with systemd, I started up a 
kde-polkit-integration app as part of my X session init, in a local 
.xinit file.
Should I do the same with the supplied polkit-gnome provided?

Any insights much appreciated. Thanks.
