GraphHopper Navigation Module: Which Mapbox API version?


can you tell me with which Mapbox API Version the GraphHopper Navigation Module is compatible?
I’m interested in using the NavigateResponseConverter, it states

Converts a GHResponse into a json that follows the Mapbox API specification

I need exactly that for the actual Mapbox API version, which is v5.

Edit: I think it’s v5 since in v4 stuff like banner instructions or bearings do not exist.
