Global List of Alexa Metadata?

Is there a simple way to list all Alexa-Metadata that is configured in openhab (together with Object-information to identify where each Metadata is added)?

Open the developer sidebar (alt-shift-d) and search for “alexa”. Under Items you should see all the Items that have alexa metadata (or which might have “alexa” somewhere else in their configuration). You can pin the Items and click the pencil icon to navigate to the Item’s page.
