Return Workflow Variables to display in Form

Here is the use case.

I have an approval workflow and the requirement is the submitter should be able to see the final result of the approval in the form. E.g, approval status and name of the approver.

For now, we can use form variables in the workflows. But, we can't return workflow variables back to the form. In form, we can only pull in the data from the context tab.

Given that our users are coming for SharePoint on-premise where the form is attached to a SharePoint item, normally this is basic requirement. They can simply go back to the form to check on the status and who approved the request.
