Hello jlucas,
I’m glad you asked. This feature has been added to the standard API and will be available in the upcoming release of WebViewer version 10.5, which is expected to be released in a couple of weeks.
To get notified for the next official SDK release you can join our announcements channel.
For platform specific notifications, such as Nuget, NPM, CocoaPods, please see the respective Apryse product documentation page.
Hope this helps!
Regards,
Maggie V.
