The video and map examples do not load an external iframe before your explicit consent. Only the button for the individual item establishes a connection to the provider. The content can then be removed again. Consent applies to that single item and is not stored permanently here.
The examples use public technical demonstration links and a general map area in Berlin, not private customer content. An external provider can change its availability or embedding rules. The Google Maps and Google Docs examples below deliberately show the state without a configured public embed instead of pretending that content exists.
