one-time skip undo send delay

I love the undo send delay, but if I close my macbook directly after sending an email, the email will not send. This leads to moments when I send an email and want to close my laptop to put in a bag, but I have to wait 30 seconds before I can do it.

Is there a way to skip this dealy just ONCE? To be clear, I do not want to change the send delay in the settings. I just want a button or keybind to bypass it on a case-by-case basis
