Data Layer events are not being picked up for the OOTB PDF viewer

​@ChinmayiSh, the OSGi config you enabled (DataLayerConfig) only powers the page and core component events on the parent page. The Adobe PDF Embed component renders the PDF inside an iframe and its events do not flow into window.adobeDataLayer automatically.

The fix is to register a PDF Embed API callback. After you create the viewer with new AdobeDC.View(...) and call previewFile(...), the returned promise resolves to an adobeViewer instance. On that instance, registerCallback with type AdobeDC.View.Enum.CallbackType.EVENT_LISTENER and pass options with enablePDFAnalytics set to true. That last flag is the key, without it you only get a minimal subset, with it you get PAGE_VIEW, BOOKMARK_ITEM_CLICK, ANNOTATION_*, TEXT_COPY, and the rest.

Inside the callback, push the event to window.adobeDataLayer with your own event schema. On the Launch side, create a rule that fires on that ACDL event name and maps the fields into your Analytics or Web SDK call.

If you have a CMP that blocks scripts before consent, both the Embed API initialization and the ACDL push need to be gated until Launch is not blocked at the time the events fired.

If you can share which AEM version you are on (6.5 or AEMaaCS) and whether you are on Launch or Web SDK, I can be more specific on the downstream mapping.
