Connect to a server with third-party authlib-injector authentication?

[Zyzzyva0381]

I have tried to manually send a request to the authentication server and get the accessToken and clientToken, and then pass them to the createBot function. Unfortunately it did not work; the server kicked the bot for "invalid session", and asked me to check authlib-injector configurations.

If you can investigate and share the specific auth protocol of authlib-injector it would help

You would also need to set authServer and sessionServer in your bot options, as it's probably trying to authenticate with your access and client tokens to mojang's servers. (and then also set the auth to be mojang)
