Is there any solution the fullscreen issue with Cypress?

I am new to cypress and I am trying to do some tests. One of the tests is to check all the buttons of a media player. However when I click the fullscreen button nothing works however cypress says the test passes. Any ideas how to get the screen to open to full? Ive tried playing with css classes but nothing seems to work.I tell cypress to click the selector, on a video player like youtube, for enlarging the screen, the test passes but the video player never opens full screen.
