Reagrding sugestions for build a OTA updates linux

I want to set for now I was doing update via adding SCP command in do-fenix-full-upgrade pre-built script where scp pointing to ota_deb directory in my host.
now I want to add notification for update so…

  • is it possible to send notification via ssh or
  • would I need to write websocket
  • is there any functionality in fenix script for OTA update task

hope some senior can put light on this question for me
