Got a few comments 🙂

General comments:

• Does not seem like the syntax: asyncapi is rendered 🤔
• I would try not to use subscribe and publish unless the channels explicitly use an event broker, otherwise, I would keep the wording to the application receive or send something.

It's the ` characters, where you highlight certain words, is rendered exactly as ` instead of highlighting the word such as asyncapi

I used the style of previous Async Hello world tutorial v2, but I will remove it
