Pass ATT consent info to WebView showing GPT ads

[ART]

Hi,
I’m using the Google Publisher Tag (GPT) inside a WKWebView with the WebView API for Ads (link).
My iOS app requests App Tracking Transparency (ATT) authorization using ATTrackingManager.requestTrackingAuthorization before calling

GADMobileAds.sharedInstance().register(webView)

How can I pass the ATT authorization (IDFA allowed/denied) into the WebView so GPT ads respect the same tracking state?
Does the SDK handle this automatically, or do I need to inject the ATT status or IAB TCF/GPP consent manually via JavaScript or URL params?
If ATT is denied, will GPT default to non-personalized ads?

Thanks!
