I am working with a client who is trying to send a PDF document for signature from Laserfiche. They have Adobe Pro, and are trying to do this directly from Laserfiche. The image below shows the LF Document Viewer displaying the Signature Sign in, but none of the actions work. I know that this works outside of LF, but is this a possibility with any plugins or integrations?

If not, is this ever going to be a feature that the Desktop or Web Clients can perform?
