How does Cypress CI/CD work without a GUI browser?

It is possible to integrate Cypress e2e testing in a CI/CD pipleline. But I cannot find an explanation how that works. Doesn't Cypress require a GUI browser to simulate real-world user intereaction with the application? How can it possible run in a terminal? How does "scrolling, clicking, drag and drop etc." be tested in CI/CD?

You can run chrome in headless mode. It just runs chrome like normally (kinda) but does not show anything
