Pretty basic but how can I press {esc} key over the page?

[MatiDiez]

Hey everyone, I'm testing a page. One of my steps enebles/disables a pop up in the page.
Some times it takes a bit longer to disable the popup on the backend, so on my subsequent test, I randomly get or don't get the pop up.

So, the easiest straight forward solution for me, is to press Escape key. If the pop up is present it will be closed, if it is not, nothing happens. So my question is:

How to I simulate pressing the Escape key?

I tried cy.type('{esc}') which obviously doesn't work because it has to be chained to a DOM element. I also tried
cy.get('body').trigger('keydown', { keyCode: 27}) but it didn't work. Any suggestions?

maybe too late but this worked for me:
cy.get('body').type('{esc}')
