I don’t want to use a third party software or a desktop program. Just JavaScript.
That is not really a solution, because the UserToken is valid only for a couple of ours. In a 24 hours stream, the user would have to open the script and enter a new token, multiple times.
Same answer like the first one.
Thanks for all of your help. But it seems, there is not even one way to get it done without a server or anything equivalent (like third parties).
