Is Ad Manager Viewability Insights safe?

Clean risk

Ad Manager Viewability Insights reads Google Publisher Tags ad slot metadata into its DevTools panel.

When its DevTools panel is open, the extension injects a script into the inspected page and listens to Google Publisher Tags ad events. It relays ad slot details such as GPT version, ad unit path, line item ID, slot element ID, size, visibility, and slot counters to the extension panel for local display.
