Converting to Selenium tests to Katalon recorder scripts

Hi All, I am impressed by the capabilities and the usability of Katalon. I have some tests I have written some time ago using selenium. But rather than using implementing the test cases I used a code generation on runtime to generate the test codes using few JSON files I have. Therefore the actual tests are in JSON format. I would like to convert these tests to Katalon scripts. Is there a proper guide I can follow to generate scripts like

by hand…
Thanks in advance…
