MaxApi.post

Hi, I've been for max for a couple of years now and trying to build something at the moment using node.js. It's essentially an art installation, that detects poses and does a projection thing. My question now is: I've got the js side of things (almost) completed, I use poseNet to detect poses and trigger sounds, that I do in Visual Studio Code. Now what I want to accomplish is to send a bang(?) to max, utilising the maxApi.post(?), to itll receive a bang, everytime one pose is detected. I've managed to send text to the max console from my js script, but I can not figure out how to send a simple bang from my js script to max msp in order to trigger videos etc. I suspect it has something to do with the dictionary in max. Anyways, anyone care to shed some light? Thank :)
