remix-auth and linked accounts

[caprica]

I've been successfully using remix-auth with GitHub, Google and email logins.

What I'd like to do now is implemented linked accounts, for example if a user logs in with their GitHub account, I want to give the option to link their Google account so I could do things like read their calendar.

I'm unclear how to go about this, is this outside of the remit of remix-auth? I've read documentation to trigger a Google sign-in flow, grab the cookies and then invoke the Google APIs but this is done outside of remix-auth, is this the correct way?

Anyone has any ideas, or an example, would be greatly appreciated, or even just a broad description of the right approach.
