How do you add the Snaptic package manager?

It should come preinstalled. If it isn’t install the synaptic package with muon.

Color me idiot grey. I found it.

It´s a learning experience. If you back click on the KDE menu and choose edit applications then drop down the ¨edit¨ options and choose ¨Restore to System Menu¨ you should be able to see all installed software on the system. I do this and then carefully familiarized myself with everything installed. Always nice to know what you have and don´t have on your system.
