I saw, that there is a possibility to make the extension to “Panel” AND “Overlay” at the same time in developer settings. If I set the ticks to both, then the extension is really displayed as panel AND overlay on twitch extension page.
But if the streamer will activate the extension, he has to decide to show in “EXTENSION-PANEL” OR at “EXTENSION-OVERLAY”
So for the streamer it seems that it is not possible to use the panel AND overlay at the same time.
Is this a bug at the moment - because of the really new function - or want twitch that the streamer could only use once at the same time? Or did I overlooked something?
