Hello , this is not documented so you need to discover it the hard way .
So lets start by the HTTP API provided by this package.
https://github.com/beyondcode/laravel-websockets/blob/master/src/Server/Router.php#L71
We are interested on this line of code

$this->get('/apps/{appId}/channels/{channelName}', config('websockets.handlers.fetch_channel'));

The controller responsible for this route is FetchChannel :
https://github.com/beyondcode/laravel-websockets/blob/master/config/websockets.php#L278

laravel-websockets/src/API/FetchChannel.php

Line 9 in 605a7fa

class FetchChannel extends Controller

So you can make an HTTP GET to the url :
http://localhost:6002/apps/YOUR_APP_ID/channels/CHANNEL_NAME
But this will give you an error , Invalid auth signature provided
The auth signature is generated like this :
https://github.com/beyondcode/laravel-websockets/blob/master/src/API/Controller.php#L264

Note: I only tested this using postman.

This is my test :

i wish this will help you .
