I'm trying to display a warning message inside a Modal or Toaster before the user closes browser. I usually get this :

enter image description here

Is there anyway to display something else rather than the default pop-up?

window.addEventListener("beforeunload", function (event) {
    event.returnValue = "\o/"
})
