30 second delay on email sends

In Gmail, I am able to turn on a setting where I can click “undo” on my emails up to like  30 seconds after I send them. This means that when I click send and then “whoops, I forgot to mention this other thing” or “oh no, there’s a typo”, I can click undo, make the change, and then send it again. I use this literally all the time in gmail and I would like there to be a similar feature in Intercom.
