How can I get the permalink of a post before it is published?

I’m trying to create a plugin that gives you a push notifications button, through the WordPress editor and I can’t find a way to get the permalink of a draft post before its status is set to published.

The predicted permalink already show up in the editor, I just can’t find how I can retrieve the same value in my code. get_post_permalink() and get_permalink() don’t work until the post is published.

Thx in advance!

You can use get_sample_permalink()

Call get_sample_permalink( $id ) or if you want to pass your own title or slug into it, the full signature is get_sample_permalink( $id, $title = null, $name = null)
