Webdynpro developed screen as a Work item to UWL?

Hi Experts,

First time working on UWL Work items.

Here is the Requirement:  We have screen developed by webdynpro. User will fill the data in screen and submit for approval. In the developed screen itself have Approve and reject options.

Work item as a developed screen in Approver UWL. Once approver double click on Work item in UWL immediately developed screen need to be open for approval.

here approver approves (OR) rejects Based on data on the developed screen.

Can you please explain with Work item integration with UWL.

Or explain ways to achieve this senario through Workflow?

How to achieve this?

Regards,
