View Users' Saved Queries as Redshift Admin?

I am an admin of our Redshift cluster. Is there a way for me to view (unshared) queries that have been saved by my Redshift users - especially decommissioned ones? I am worried that following the departure of some colleagues (and old roles that have been swapped out by our IT team), we may have lost very valuable queries that were saved via Query Editor. I am aware that I can view SOME recent query history via tables like STL_QUERY but I've already discovered there's pretty much no overlap between Saved Queries and that content.
