Then I am maximally impressed that any Trumpians even know what that is, much less know about any content therein.

That said, it may be a valid point, since the document at issue indeed has not been found (yet) in Donald's possession. Terribly unfortunate that Bedminster was never searched, one more casualty of DOJ/FBI foot-dragging.

No doubt witnesses will be testifying about what documents were being discussed during that session. At one point Trump says, "Here, give me that" which indicates that the doc was in the hands of someone besides himself and I've no doubt that there is already grand jury testimony by that person describing what they were holding. When the prosecution has that person on the stand, they will then show them the copy DOJ has and ask them to verify it was the same doc and how they know. And so on.
