Showing a SweetAlert in fullscreen

[vnihoul77]

We're looking to display a SweetAlert popup in fullscreen. Here's what we tried so far:

CSS

.fullscreen-swal{
        z-index: 9999 !important;
        width:100vw !important;
        height:100vh !important;
        }

JS

    customClass: "fullscreen-swal",
    autoHeight: false

The popup is not showing almost (70%) fullscreen, so it's bigger but not fullscreen. What am I missing?

Swal.fire({
  grow: 'fullscreen'
})

Thanks for your answer, however using this parameter still leaves borders/space around the modal. Screenshot: https://imgur.com/a/FTR9xXq
