Setting Headers directly in Katalon


In order to test, I must modify headers first and I’m not quite sure how to do so in Katalon
For example

Action: ADD

We have been using google extensions - modify headers when manual testing

search the doc about how to create test objects scripted

Do you have any specific docs you would recommend. I looked all over and I cannot find anything that will work. I’ve been stuck on this for over 2 weeks and I can’t move forward with testing because I can’t get onto the website through katalon without headers because I keep getting errors/headers attached to my url when trying to run a basic script in manual mode.
