What’s next after the court date of small claim in Harris Count Justice of the Peace?

Judge ruled in favor of us and it was a default judgement since the defendant didn't come. Judge was satisfied with our evidence and the defendant admit and never denied anything in text messages and phone calls.

It's safe to say we won the small claim, but what's next? The website just shows judge ruled in favor of us and against the defendant who has to pay the amount with 7.5 interest rate. That's all the website says.

I called the court, but they say I have to do research in order to find out what's next. I think she also said that court isn't gonna send letters about anything.

I will call the court again and hope that different person picks up, but what do I do now to retrieve the money from the defendant?
