How to acces map data from isaac.map.Map component

Hello everybody,
I’m trying to test my own localization system. To do this I need to interact with map data that are handled in Isaac by the map component:
isaac.map.Map
However from the documentation seems that there are no incoming/outgoing messages from the map component but the data is directly accessed by all the other components.
I would like to have an example on how to access this data like all the others isaac.map.xxx components do.
I would like also to ask if in future releases there will be the possibility to transfer map data among codelets through messages.
I found a topic that refer to a similar problem https://forums.developer.nvidia.com/t/how-maps-are-handled-by-isaac-sdk/115176?u=luca.nobile; however it doesn’t seem to be solved yet.

Thanks in advance,
Luca
