How to use Read–Eval–Print Loop (REPL) / Interactive / Console Mode using Katalon?

How do I use Read–Eval–Print Loop (REPL) / Interactive / Console Mode using Katalon?

I want to be able to write code to open browser in an interactive command line, and then the browser should open.

Then write code to navigate to URL and find element in the command line, then the previously opened browser will execute these.

It is like Python/Ruby interactive REPL sessions.

I want this to help test interactively.

How can I do this?
Any suggestions?
