Epicor P21 2020.01.3913 - how to delete an 'approved' journal entry?

I’ve mistakenly posted month end adjustments into the wrong period and need to remove the entries. I know I can ‘reverse’ which will suffice, but will leave all the transactions visible. I’d like them gone as it’ll make the rest of the month ends so messy. I might just have to live with this mistake, but I can see the option to delete, but when I check the box, it tells me approved transactions can’t be deleted. And I can’t seem to find out how to unapprove. Any help is appreciated

I’m pretty sure once you’ve posted you are done for
