Thank you for answer!
Most of streamers always have opened stream manager with live stream.
By now stream manager supported overlay extension, but only problem is wrong JWT initialisation.
In my extension it is a necessary to create a poll in overlay (not in live config). Just becouse you created poll variant in right position like this.
Just to summarise.
Right now overlays is working in stream manager but initialised with wrong credentials (role:“viewer”, opaqueID: “Ai1823anajsdn”)
If broadcaster open their stream by link Twitch all work correctly and role: “broadcaster”, “opaqueID”: “channelID”
I think it is a bug that overlays initialised with wrong credentials in stream manager.
And I don’t catch your point about security. I’ve used twitch JWT to authorise the request. There is no security problems.
