Navigraph FMS data manager and FS2020

I usually fly a Garmin 1000 in a Cessna 172. The Garmin 1000 does not have charts for some airports like USMU. Navigraph has STARs, SIDs, Approachs, but Flight Simulator 2020 doesn’t. How do I add this data to Flight Simulator 2020? Did they appear in the Garmin 1000? what should be done?
