Unable to change UID due to deleted duplicate UID

Hi there,
I have a post that needs to have a specific UID, there were previous versions of this post that used the particular UID I need but I archived/deleted them all before finding out how to preserve that UID. Now I’m unable to access the old posts to duplicate and recreate through this route: https://user-guides.prismic.io/en/articles/1546584-error-this-value-is-already-used-by-another-document. Is there a way to free up the UID once the other posts are no longer available?
Thanks!

Hey @zach, thanks for reaching out!

The article you found is the correct way of recovering a UID.
