Integrate Approval Process functionality into Skuid

I want to recreate the Recall Approval Request button in Skuid. I know how the link should be set up, but I can’t get the Id of the ApprovalProcessItem to render in the URL because the button is on a page title block that has Opportunity selected as the model. Transversely, I tried a page title with ApprovalProcessItem as the model and I can’t pull the Opportunity Id (aka TargetObjectId).
