Demo of ziti tunnellers for onload / offload traffic

Checking if there are any demos that show how to use these commands.

I would like to better understand how to use them.

Specifically, I am looking for alternatives to the need for a Golang reverse proxy server using the ziti SDK to

  1. onload data onto the fabric
  2. offload data from the fabric

I have used a desktop tunneller to offload traffic, but I am assuming that that this can also be configured at the server / router level.

Hence… my interest in how to learn to use these tunneller commands

In relation to onloading traffic to the fabric, the only option I have used is the ziti SDK to create a ziti listener

Are there ways to onload data into the fabric using these tunnellers?
If so, a short demo would be greatly appreciated.
