PlatformIO ide and Arduino Portenta Machine control using zenoh-pico library

hi, newbie in the PlatformIO IDE…i want to develop a peer-to-peer communication between my system and the arduino Portenta machine control…say like this…there’s a publisher(publish the topic) from the system turning the led state on and off in the arduino machine control…and there’s a subscriber(subscribe the topic) from the Arduino portenta machine control handling the command from the publisher…I really don’t have an idea of developing this process. But i tried the examples Digital Output from the Arduino_Machinecontrol library(found in this] github page … uploaded to the board from the platformio IDE…worked fine.
If you guys have any idea how to do that, let me know…it would be so greatful.
Thanks in Advance.
