I want the user to be able to sign in with multiple accounts, then switch between them similar to how you switch account in discord. However, I could not find any information on how to implement this with next-auth (or just implementing it in general). How can I implement this? Tysm in advance!

For additional context, I am using appdir, and there is an external server that I will be authenticating against, which returns me a JWT when the user signs in (me sending them a request with username & password). This server is outside of my control.
