Serverless Tutorial Walkthrough

I am new here and to serverless, I am doing the walkthrough for a full-stack app using AWS. The UI has changed quite a bit since recording the video, I managed to find what i needed to link up a lambda function to an endpoint, but it looks like there should be a way to test within the AWS console? I know I can probably use postman, but at this point I felt like I should ask around and otherwise press onward with the tutorial. I just was looking for a suggestion, if this is really any different than hitting the endpoint with something like Postman.

EDIT: it looks like I was in the wrong spot, AWS now asks you to chose the type of api at the start and separates them ie. HTTP, REST, etc… The UI now looks the same as the one in the video.
