By default, markups only exist within the Workspace where they were created. However, you can publish markups to Content to share them with other Workspaces or save them for future use. To do this:
Select the markups you want to publish.
In the three-dot menu in the, select “Publish to Content.”
You’ll then be prompted to choose a location in Content to save the markups.
Watch-its
Published markups inherit the data access permissions of the Content folder where they’re saved, which may differ from the Workspace permissions.
When selecting multiple markups, if your selection includes both published and unpublished items, only the unpublished ones will be affected by the “Publish to Content” action. Markups already in Content will remain where they are.
