How to assert on HTTP response code?

I am learning how to write assertions on a REST API , and the responses are Json messages.

Now, I would like to create an assertion on the HTTP response code, so I can check if the request is accepted.

For example: inserting an assertion on HTTP 200 OK is a good assertion (I think).

My question is. Which assertion type do I need to choose? And what would be the exact code?

I can select Invalid HTTP Status Codes, but this only allows me to enter invalid HTTP codes. (if I enter 200 I get an assertion failure with message "200 is in invalid list of status codes" .
