How to highlight HTTP requests in Github Markdown? - http

Question

I'm writing my README.md file for a Github repository, which contains some requisitions written for manual testing the application. The tool I use to make the manual tests is the REST Client extension for VSCode.
I want to show the manual tests highlighted on the front page of the repository, on the README. If it was some javascript, I could write something like:
```javascript
console.log("Hello World")
```
Github would recognize the code between the ``` and highlight it as javascript. But how can I do it for HTTP headers like these ones?
```http
### Expect { message: 'Wellcome to TestsAPI'}
GET http://localhost:5001/
### Expect code 201 and info about the new user
POST http://localhost:5001/user
Content-Type: application/json
{
"name": "Pitossomo",
"email": "pitossomos#hmail.com"
}
### Expect code 400
POST http://localhost:5001/user
Content-Type: application/json
{
"name": "",
"email": ""
}
```
In the example, there are 3 requisitions that can be made my the VSCode REST Client extension, separated by the ###. I put the ```http but it does not work, maybe there is some other word to refer to http headers?
Searching in google I've found the reference for the documentation of Highligh.js, but it does not specifies the word used by Github
