Screenshot web element in JSON format

hello, I want to screenshot my web element response into my katalon report. However, the response captured are in raw format. I have installed JSON formatter extension in my browser but it still captured in raw format. is there any way to enabled my web element response to be captured in JSON format? Because when I copy the exact same web url in my browser, the response are in JSON format, but when I run using Katalon, the response captured are in raw/text format.
