[Bug]: Xbox IDP Linking on email

[alex-fusionauth]

What happened?

Question on xbox signin, I have this setup and it is asking for the correct scopes but it is not mapping email correctly.

It appears that we are calling https://login.live.com/oauth20_token.srf first and it correctly returns

{
  "ver": "2.0",
  "iss": "https://login.live.com/",
  "sub": "AAAAAAAAAAAAAAAAAAAAAAWtIcTAtQJ_P7G1LD0tzqk",
  "aud": "02bd0c68-d591-46de-9464-01442f995412c",
  "exp": 1746296761,
  "iat": 1746210061,
  "nbf": 1746210061,
  "name": "Alex Patterson",
  "preferred_username": "me@hotmail.com",
  "oid": "00000000-0000-0000-0011-d90227bb061",
  "email": "me@hotmail.com",
...
}

After this call we call the xboxlive endpoint for https://user.auth.xboxlive.com/user/authenticate which returns

{
  "IssueInstant" : "2025-05-02T18:26:01.5548078Z",
  "NotAfter" : "2025-05-03T10:26:01.5548078Z",
  "Token" : "xyz"
  "DisplayClaims" : {
    "xui" : [ {
      "gtg" : "Me@202",
      "xid" : "2533274855507913",
      "uhs" : "11446281356715118283",
      "agg" : "Adult",
...
    } ]
  }
}

I want this to link to email which was in the oauth call, but it seems to only want to use my gamertag.

5/2/2025 06:26:01 PM Z Linking strategy [LinkByEmail]
5/2/2025 06:26:01 PM Z `Resolved email to [null]` -> should have `me@hotmail.com`
5/2/2025 06:26:01 PM Z Resolved username to [Me@202]
5/2/2025 06:26:01 PM Z Resolved unique Id to [2533274855507913]
5/2/2025 06:26:01 PM Z Identity provider returned a unique Id [2533274855507913].
5/2/2025 06:26:01 PM Z A link has not yet been established for this external user.
5/2/2025 06:26:01 PM Z The user with the email address [null] does not exist.
5/2/2025 06:26:01 PM Z The identity provider was unable to reconcile the email address. An email address is required to complete this request and link by email.

So I am wondering if we should change the logic in the IDP connect??
