Include additional field in session data

Hello! I have an additional field username that I want to be included in the session data, but I don't know how to do it. 
import { betterAuth } from "better-auth";
import { drizzleAdapter } from "better-auth/adapters/drizzle";
import { db } from "./db/index";
import * as schema from "./db/schema";

export const auth = betterAuth({
  database: drizzleAdapter(db, {
    provider: "pg",
    schema,
  }),
  user: {
    fields: {
      name: "display_name",
    },
    additionalFields: {
      username: {
        type: "string",
        defaultValue: null,
        input: false,
        unique: true,
      },
    },
  },
  socialProviders: {
    google: {
      prompt: "select_account",
      clientId: process.env.GOOGLE_CLIENT_ID!,
      clientSecret: process.env.GOOGLE_CLIENT_SECRET!,
    },
  },
});
import { betterAuth } from "better-auth";
import { drizzleAdapter } from "better-auth/adapters/drizzle";
import { db } from "./db/index";
import * as schema from "./db/schema";

export const auth = betterAuth({
  database: drizzleAdapter(db, {
    provider: "pg",
    schema,
  }),
  user: {
    fields: {
      name: "display_name",
    },
    additionalFields: {
      username: {
        type: "string",
        defaultValue: null,
        input: false,
        unique: true,
      },
    },
  },
  socialProviders: {
    google: {
      prompt: "select_account",
      clientId: process.env.GOOGLE_CLIENT_ID!,
      clientSecret: process.env.GOOGLE_CLIENT_SECRET!,
    },
  },
});

I tried adding returned: true to the property but it still doesn't work. 
   additionalFields: {
      username: {
        type: "string",
        defaultValue: null,
        input: false,
        returned: true,
        unique: true,
      },
    },
   additionalFields: {
      username: {
        type: "string",
        defaultValue: null,
        input: false,
        returned: true,
        unique: true,
      },
    },

export const { signIn, signOut, useSession } = createAuthClient();
import { createAuthClient } from "better-auth/react";

export const { signIn, signOut, useSession } = createAuthClient();
