Dynamic scope support?

[yuklai]

I like to ask how does next-auth officially support dynamic scope.
I.e. asking for the scope of an auth that is regularly needed, and ask for incremental scope when the feature calls for it.

For example, ask for "email" and "openid" when user sign in, but ask for "email send" and "email read" later when it's necessry.

I figured that the signIn call can pass ing extra scope. e.g.
signIn(providerId, { callbackUrl }, { scope });

But for me (testing with azure-ad) the new scope and the refresh token is not stored in Account.

What is the official supported way of implementing dynamic scope? Thank you!
