Will be returned? Or thats what you are getting?
Sorry.
This is the actual code I got.
In the frontend, I believe it is userId=opaqueID=window.Twitch.ext.viewer.opaqueId that you can get when onAuthorized.
I have tried to use this ID to listen but did not get any notification.
window.Twitch.ext.listen(‘whisper-’ + window.Twitch.ext.viewer.opaqueId
ChannelID is also obtained from the communication from the frontend to the EBS and is used for private use, so I am sure it is correct.
