Where to paste this telegram discuss widget code?

Telegram has some very useful bots and widgets which integrate nicely with your websites.

I’ve already integrated telegram notification chat integration plugin.
But now I wanted to integrate (perhaps new) DiscussBot with my website.
For this I’ve to add this code given by telegram discuss bot somewhere (perhaps) in my Discourse website.

Can anybody pls guide as to where can I add this code so that the telegram comments/discussion could be integrated with my site?
