How to to enable the selection of POV members when running report package?

Summary:

I am currently developing a report package in Narrative Reporting and need assistance regarding the configuration of the Point of View (POV).
I have dimensions configured in the POV of the report, and when previewing the report in the designer, I can select the members as expected. However, when executing the report package, I am unable to select the POV members — the values remain fixed and cannot be changed by the user.

What we need is to enable the selection of POV members at the time of running the report package, so that end users can choose the desired period, entity, or other dimension members for visualizing the report.
