Module Hook into Localization

Looking to hook into the Translation manager that Ignition provides through a custom module. I want to be able to load many translations from the provider but also populate many of the translations as well.

Taking a look at [feature-14961]Add system.util.modifyTranslation to GW/Perspective - #10 by PGriffith
It looks like I need to use reflection in order to access the LocalizationManager from the Gateway side. Is there an example of how to do this?

I see how to modify and get the translations once I have this (using the add term and creating diffs) but need help actually getting the initial object from the gateway and then saving this object to the gateway.
