Show modal on route change
[issue link]Hi
I need to show a modal on route change. if a file upload is already in progress.
After the upload the user moves to another page.
So if the user clicks on some other button while the upload is happening I need to show this modal.
Is there a hook in pages which I can implement to handle this.
Basically I am looking for a hook which is called when the user leave a particular route.
