That integration link will only show tasks within that workflow. I've tried to deconstruct and reform the parameters, but it has not been fruitful.
Clearly there is a method which is used to access each section fully: Document trays, Search, Lists, Tasks ... this happens when those buttons are clicked, but it appears to be purely javascript.
My goal is to use the URL redirect after a form submission to take the user to their Tasks. There, they view the merged data and confirm the document. (Because there's no way to see the document prior to submitting the form.)
