Consul with nodejs

Hello geniuses, how are you?
I’m wanting to do an internship with, I’m running local on linux,
I have consul installed, I raise the agent, and create two services in nodejs with the consul client that register the service, with the library consul - npm
I’m trying to get them to communicate with each other through the consul, but I can’t close the loop.
The consul detected them, but I don’t understand how to call from one micro service to another, does anyone have experience?
