How download a BI report in PDF Output using Smart Action on redwood page?

Summary:

On a CX Sales Redwood page, we’ve added a “View PDF” smart action button. The requirement is that when the user clicks this button, it should trigger a BIP (BI Publisher) report in the backend and automatically download the PDF output.

Work Completed So Far:

• We have developed a BIP report and attached a PDF template to it.
• A function has been created in Application Composer, which uses the ExternalReportWSSService SOAP service to trigger the report.
• The smart action is configured and linked to this function.

Assistance Required:

We need help with the code/configuration that enables automatic download of the PDF report
