I'll add that what a lot of non-developers seem to think is documentation is not actually worth very much. For instance, a 2 hour recording of a zoom meeting tagged only with a date and general topic is worth so much less than a searchable text guide on the same topic. Recording a meeting is not documentation! Especially if it's not tagged properly and made available to the people who need it. It's also impossible to update a meeting recording of course so it's guaranteed to be out of date after enough time passes, requiring that meeting to be held and recorded again.

Other things that I see treated as documentation when they're not: slack messages, uncommented code ("self-documenting" code exists, but it's much rarer than management seems to insist), vague jira tickets, some guy who worked on the app 5 years ago and is happy to answer questions even though he's in a new role now, etc.
