Hi there,
I try to embed a peertube (onsite) video to our confluence site (data center onsite) with the Widget Conntector.
In my mind, peertube and youtube have similar/equal conditions to be used as an embeded video in a confluence page.
I added the peertube URL to the allowlist as a domain and the check is green for the URL of the video.
But I only see a picture and the domain name:

HTML-App is disabled for security reasons.
Does the Widget Connector need HTML-App features enabled or is peertube not supported / usable by confluence ?
I don't see any errors or hints in logfiles by grepping for peertube ir widget in log directory.
What else do I need to config to use a peertube video as embeded video on a confluence page ?
Best wishes
Frank
