I want to set a value to the developer Configuration segment of my Extension from a 3rd party system using the Twitch API, as per https://dev.twitch.tv/docs/extensions/reference#set-extension-configuration-segment
The Extension is created within a Twitch Developer organisation.
What value do I use for user_id within the JWT?
Do I use the user ID of the organisation? If so, how do I obtain this value?
