Hello, can someone tell me how I can grab the unique task value (looks like the instance ID but isn't....I'm assuming it's the Resume ID) and write it to a template field before the task is assigned (or how to write to a document after the task is assigned)?

Basically we're trying to create a tab in the Doc Viewer that will display a forms task related to the document open in the viewer.  I've done this before for on-prem by grabbing the Resume ID value from the Forms DB but not sure how to do this on Cloud
