Multi provider data in one session

[hamen]

Hi all,

I'm working on a web app that started with the Twitch authentication.
Over time, we decided to add integrations with the Twitter API, the YouTube API and other social networks.

I wanted to leverage Next-Auth to easily get access tokens from Twitter/YT/etc. having the user to login again with Next-Auth.
Unfortunately, as you can imagine, once I have the user login with Twitter, after they logged in with Twitch, I lose the session info (Twitch tokens).

Now, I understand that probably what I'm doing looks like an abomination, but I'm new to Next and BE development in general, and I need your help to find the right approach.

What do you think I could try to pull it off? Thanks,

Ivan
