Navigation: TomTom app not listed

If I'm clicking onto a point > navigation icon, I can choose from some external navigation apps. But "TomTom app" (former named "AmiGo") is missing.

Btw: Their 2nd app ("TomTom GO Expert") https://play.google.com/store/apps/details?id=com.tomtom.gplay.navapp&hl=en is working well with Locus' naviagation icon.

There's been a thread in the past, but the problem is still present: https://help.locusmap.eu/topic/27692-tomtom-amigo-not-listed-as-navigation-app-in-locus

As mentioned in the old thread, if using other apps like c:geo or Android contact-app, I'm able to choose TomTom app. Even in Locus, if clicking onto the point > "sharing icon" (not navigation icon!) > further map providers :-)

So maybe the problem is that TomTom app is not reporting itself as a pure Navigation provider to Android, rather than a "mapping app"? On the other hand apps like c:geo or contacts are offering TomTom-app if clicking onto their "Navigation" icon.
