That is true but there is still a process. You have to mark the document as declassified and add a date and a signature. And you have to remark all existing classified copies of that document as unclassified in the same way. All classified documents are numbered. If one turns up in the wrong place unprotected security will know whose copy it is. All of these need to marked unclassified.
I really hope that Trump does not think declassification is just a wave of the hand by an outgoing President. It is more than that.
