Extension doesn’t appear on Google Play Console in-app product pricing

Summary:

When editing prices for an in-app product in Google Play Console, the extension doesn’t show up at all. This seems to be related to Google’s recent update of the IAP pages — the new layout isn’t supported by the extension yet.

Expected behavior:

The extension should load on the updated IAP pricing pages and detect the price editor the same way it does for apps and subscriptions.
