How can I display line items in the SAP BTP Build Process Automation (Workflow mgmt)

Hello experts,

I would like to get PR header and item data and display it on the workflow mgmt.service to execute approval process. Is it possible to display the line items on the screen?

Also, I will be using oData to fetch the values from the backend. I will create backend service to expose the oData. Is this a right approach?

Archana Shukla and other experts?
