Add or Build HTTP Request TestStep to Test Case through Groovy Script

Hello,

I would like to create a new Test Step to an existing Test Case, I would like this to be an HTTP Request type.

I've seen and completed examples of creating Groovy Test Steps to an existing Test Case, see below:

def project = context.testCase.testSuite.project;
def testSuite = project.getTestSuiteByName("Library");
def testCase = testSuite.getTestCaseByName("Modified Transactions");


def newStep = testCase.addTestStep("groovy", "HelloGroovy").setScript("log.info 'Hello'");

However, I would like to add an HTTP Request type and complete the necessary properties, endpoints and request, etc...

It looks like this post is discussing somewhat what I want to do, how can I find the definition of all the step types, it only has EMAIL?

Any help is most welcome.
