Thank you both for your answers.
A few specification, and I will also contact the support.
I am trying to link to another streamer page using a link in the overlay. There is maybe another way to do so than using a link but I did not found how (my excuses if there is).
I am trying to iframe a twitch player (from the API) on another player (the current one). It might seems odd but I do have a good reason to do it.
I have to confess that I already tried as a local test, and it seems to work, but I do not want to do it if this is forbidden by your policies. My supposition is that it is working become the Iframe is not there during the loading of the page, but it is build by the JS I call from your API.
1.3 Extensions can include audio only if they include controls which allow viewers to adjust the volume, and by default, these controls are set to off/muted.
(I’m fairly sure that video/component overlays are also just not allowed to play audio at all but I can no longer find that rule)
Video over video is a UI nightmare of users. And essentially doubles the bandwidth involved for the page… Or gets weird if you for some reason overlay the same stream, which then overlays the same stream which then overlays the same stream, and so on
There are lots of things that work on local test but don’t on hosted test or above.
It won’t work on hosted test (where the enforcement policies operate better, due to how web browsers work and the nature of your local test, local test will generally not apply policies correctly)
In addition it won’t be permitted past the review process.
For panels just a list of domain names, so for Twitch just twitch.tv are you saying you have entered this and resulted in an error that is observed in chrome inspector when clicking a link? (other inspector tools are available)
