I know the Vimeo domain privacy issue has been discussed here several times. I'm using Vimeo pro however I don't want to use video direct link as H5P reveals it in the inspect element. Plus Vimeo benefit besides transcoding is domain-level privacy.
So I'm using h5p Column with iFrame Embedder and a quiz. This works fine on Desktop. I able to embed Vimeo videos with this URL in iframe embedder activity;
