Query navdata airway via simconnect

using SimConnect_RequestFacilityData we can query navdata of Airport, Waypoint, VOR and NDB

but not the airway, is there any way we can query the airway info, like given the name, we can get list of waypoint inside that airwau

You get the airways from the Route object for each waypoint. The API is is kind of inverted, instead of starting from an airway you start from a waypoint.

yea i know about that, but my case is i know airway name, and list the waypoints if the airway
