Open annotation file for a pdf

In DEVONthink, a record has an annotation property, so I think exposing that property in those already available for a DEVONthink item would be sufficient.

I was hoping DTTG 3.8.2 would expose the Annotation UUID property in Shortcuts (see also Make “Annotation” available in DT items in Shortcuts - #4 by mdbraber). Hopefully it will something considered for a future update!
