Support for Arduino Nano Matter Board

Further to the post regarding support for the Arduino Nano Matter ( Support for Arduino Nano Matter ), when i review the list of compatible boards there is nothing listed for this board.

I am trying to build an initial platform.ini file, consisting of release and debug, but I’m at a loss past

  • platform=platform-siliconlabsefm32

i have no idea what to put in for the board, and how to configure the debug setting for that environment. Does anyone have an example they could share? or any guidance.
