Accidentally gave wrong keyword for auto-dm link, over 200 commenters didn't receive DM; is it possible to fix this?

I made a post for my company telling people about a live debate coming up on Sunday. I told people to comment “DEBATE” to get a link in their DMs to the livestream. But then while setting up the automation I brainfarted and made the keyword “WATCH” instead. I fixed the keyword when I noticed the mistake several hours later, but over 200 people commented the incorrect keyword before I noticed. None of them got a DM. Is there any way I can get the link to all those people’s DMs without manually going through all 200+ of them and sending the same DM over and over?
