Using Here3 for RTK GPS without using Mission Manager

I’m working on a project that needs a localization solution such as an RTK GPS fix. We have a Here3 rover receiver, a Pixhawk2 Cube, and a Here+ base.

The tutorial describes how to set up a Here3 using Mission Manager. However, this system needs to be able to operate autonomously, without a user interface. Mission Manager requires a person to operate it. Is there a way to get an RTK fix without using Mission Manager at all? For example, is there some kind of software library that can send all the RTK-related information that Mission Manager sends? (I think they’re called “RTK corrections” or something like that?)
