Years have passed. Selenium4 has been released, which provides Chrome DevTools Protocol support. Selenium4 is what @Jens.gr wanted.
5. Support for Chrome Debugging Protocol
Selenium 4 comes with native support for Chrome DevTools Protocol. This means QAs can now use Chrome development properties like Fetch, Network, Profiler, Performance, Application cache, and more. QAs can also leverage the APIs offered by Chrome DevTools to simulate poor network conditions and perform geolocation testing.
Using this API will also help developers or QAs to test and resolve critical bugs for specific web-pages faster and on the fly.

Unfortunately Katalon Studio is NOT yet ready for Selenium 4. I am afraid KS is getting behind.
