I'm trying to send and receive events from an embedded webchat which follows the code for the website from this example https://github.com/ryanvolum/backChannelBot and the bot implements the code from Bot framework get the ServiceUrl of embedded chat control page answered by ezequiel
Here's how it all looks in my setup index.html
<!DOCTYPE html>
<!--
NOTE: This sample requires a bot which can send and receive specific event messages. Follow the instructions on
https://github.com/ryanvolum/backChannelBot to deploy such a bot.
This is a sample HTML file which shows how to embed an instance of WebChat which listens for event activities. For the sake
of demonstration it specifically listens for events of name "changeBackground". Using the backChannelBot sample
our page can listen for events of name "changeBackground" and send events of name "buttonClicked". This
highlights the ability for a bot to communicate with a page that embeds the bot through WebChat.
1. Build the project: "npm run build"
2. Start a web server: "npm run start"
3. Aim your browser at "http://localhost:8000/samples/backchannel?[parameters as listed below]"
For ease of testing, several parameters can be set in the query string:
* s = Direct Line secret, or
* t = Direct Line token (obtained by calling Direct Line's Generate Token)
* domain = optionally, the URL of an alternate Direct Line endpoint
* webSocket = set to 'true' to use WebSocket to receive messages (currently defaults to false)
* userid, username = id (and optionally name) of bot user
* botid, botname = id (and optionally name) of bot

I've tested sending message activities which works fine, however trying to send an event from the bot to the webpage or from the webpage to the bot after receiving a message doesn't do anything.
The webpage says that BotChat is not defined at both but I'm not sure why
var params = BotChat.queryParams(location.search);
and
var botConnection = new BotChat.DirectLine({
in index.html
All of my app secrets/id and directline secret are added. I feel like the problem might be how I'm adding my secret and url in index.html but I'm not sure how I would set it all up
