Hello all,

We're using the new app router and attempting to use the new generateMetadata function/Metadata API to set the page title for SEO purposes. For static public pages, this is fine -- we're making a call to our graphql server and getting the page title via the ID. However, for private pages, we'd like to only display the title if the user is authenticated and has access. We're currently using auth.js but this applies to any auth system we might use (we're considering switching due to unrelated limitations/suboptimal DX with that library) -- how do we use current client state in the generateMetadata function in general? Another way to phrase this: how do we set the page title for client components (the next step we'll need after this anyway)?

Side note: just to be certain, the generateMetadata function is only exposed server-side, right? So we can use server-side secrets safely?
