Which map is used by "navigate" app?

I have several maps installed on my Garmin fenix 6 pro (OSM based 3rd party map for Germany, as well as an original Garmin topo app for Germany (purchased), special maps for the Alps, ...). For hiking, biking etc. one or multiple apps can be activated and deactivated via the settings menu of that specific activity. However, when using the stand-alone "Navigate" app, I wonder which map is used for the around me, POI or "use map" feature. There is no option "configure map".
