after some testing and debugging i found the possible solution.

I have to add in the Map block:
  activeMapType: mapDisplay.supportedMapTypes[6]

The suggested solution provided by the docs to use
  activeMapType: mapDisplay.supportedMapTypes[MapType.CustomMap]

does not work because MapType.CustomMap evaluates to 100 (here at Qt 5.15).
I don't know is this is a bug or intentional.

I do not like hardcoded values (here: 6) because it may change in future. Any
way to solve this ?

kind regards
