How to test file inputs with Cypress?

How can I write an e2e test of flow that requires interaction with the file Input DOM element?

If it's a text input I can interact with it (check value, set value) etc as its a DOM component. But If I have a File Input element, I am guessing that the interaction is limited till I can open the dialog to select a File. I can't move forward and select the file I want to upload as the dialog would be native and not some browser element.

So how would I test that a user can correctly upload a file from my site? I am using Cypress to write my e2e tests.
