i am currently searching for a way to login into the Twitch-API using an already given id-token (oauth or even better oidc) with or without a NodeJS backend.
Background: I am using firebase connecting to various services next to Twitch-API such as Youtube (Google API), Twitter and Co. I want to use my id-token for each service.
The official documentation doesn't tell if that is possible or maybe i just couldn't find it. Hopefully there is a solution just not yet documented.
I will struggle with the same problem using the other services aswell.
Thanks alot
