[uMap] is there a way to export the map properties?

I know that in uMap, objects in map layers can be exported to kml, gpx or geojson. But I've not found a way to export the complete map/Layer (including the map properties/settings).

Basically I would like to make a backup of the maps and layers I created without loosing the map settings. The only thing I could do is to clone a map. But that's not my preferred solution. Thanks for commenting.
