Forwarding Options

1. Using a deployed telegram bot
2. Using your own telegram bot
3. Using an HTTP callback

Option #1 - Deployed Bot

You can forward the messages using a deployed bot.
I've deployed one for personal usage (but you can use it too), the default field values contain its data. If you don't trust me (or anybody else), feel free to clone the bot repo and deploy it yourself.
Here is a picture of the interface:

You just need to fill out the login field (and the other ones in case you've deployed your own bot).

Then press Save and open the generated link in the browser or the telegram app. The button in the main menu becomes green.

You'll receive a confirmation from the bot, and now forwarding works!

Option #2 - Your Telegram Bot

In this case you'll need a bot token + your telegram chat id. You can read how to get these here.

Option #3 - HTTP Callback

The app can forward messages to your http endpoint -- simply provide the callback address and press save. You may additionally specify the desired HTTP method, URI parameters, and a JSON payload.

Managing Settings

You can reset the settings by pressing the green round button in the bottom right corner. Tap accept to confirm. This will also turn off forwarding.
