Calling signIn.social with extended field data.

So I've added an additional field on my user in my server side auth

user: {
  additionalFields: {
    username: {
      type: "string",
      required: true,
      unique: true,
    },
  },
},

user: {
  additionalFields: {
    username: {
      type: "string",
      required: true,
      unique: true,
    },
  },
},

The issue I'm running into now is once I try to sign in with OAuth, i.e.

const data = await authClient.signIn.social({
  provider: "google",
  callbackURL: "http://localhost:3000/dashboard",
});

const data = await authClient.signIn.social({
  provider: "google",
  callbackURL: "http://localhost:3000/dashboard",
});

The issue is I get an error because there is no field for the username now.

Is there any way to pass in additional/extended fields in social sign ins?
