nextauth extend the profile values strava - next.js

Question

I am trying to extend what is returned in the StravaProvider profile() in nextAuth
pages/api/auth/[...nextauth].js
export default NextAuth({
providers: [
StravaProvider({
clientId: process.env.STRAVA_CLIENT_ID,
clientSecret: process.env.STRAVA_CLIENT_SECRET,
profile(profile) {
// LOGS FINE IN CONSOLE
console.log("profile", profile);
return {
id: profile.id,
image: profile.profile,
name: `${profile.firstname} ${profile.lastname}`,
// THE FOLLOWING DOES NOT RETURN
profile: profile,
};
},
}),
],
How do I expose the full profile object?. It's only returning the image and name.
In my console log - within my StravaProvider of profile - I can see the whole object, but can't seem to return it?
If I assign profile to the name key this works. I seem to be limited with the keys I can add?
StravaProvider{...
profile(profile) {
return {
// THE FOLLOWING WORKS
name: profile,
};
},
The returned session object from my initial example and how I am accessing it is:
const { data: session } = useSession();
console.log(session);
{
"user": {
"name": "JOE BLOGGS",
"image": "https://dgalywyr863hv.cloudfront.net/pictures/athletes/2909982/3009569/1/large.jpg"
},
"expires": "2023-02-03T13:39:01.521Z"
}
I realise I can use a callback and modify the session, but I need the entire profile there in the first place from the Provider to do that.
