Google LinkSocial Additional Scopes

Hello! I am using Google Oauth as a provider and attempting to follow the documentation to allow users to add calendar scopes after the login, the below correctly adds scopes, but once a user logs in with the standard oauth again that overwrites the additional scopes. I've been trying to debug this for a bit but can't figure out if there is supposed to be standard better-auth management for this or if I need to add some hook to the database to make sure we don't overwrite the scopes. Tahnk you! 
{typescript}
      await authClient.linkSocial({
        provider: "google",
        scopes: ["https://www.googleapis.com/auth/calendar"],
      });
{typescript}
      await authClient.linkSocial({
        provider: "google",
        scopes: ["https://www.googleapis.com/auth/calendar"],
      });
{typescript}
import { betterAuth } from "better-auth";
import { nextCookies } from "better-auth/next-js";
import { drizzleAdapter } from "better-auth/adapters/drizzle";
import { db } from "../db";
import * as schema from '../db/schema';

if (!process.env.BETTER_AUTH_SECRET) {
  throw new Error('BETTER_AUTH_SECRET environment variable is not set');
}

export const auth = betterAuth({
  // Add secret for encryption and session handling
  secret: process.env.BETTER_AUTH_SECRET,
  
  // Database configuration
  database: drizzleAdapter(db, {
    provider: 'pg',
    // Map model names to schema objects using lowercase to match schema definitions
    schema: {
      user: schema.user,
      session: schema.session,
      account: schema.account,
      verification: schema.verification
    }
  }),

    modelName: "account",
    accountLinking: {
      enabled: true, // Enable account linking
      trustedProviders: ["google"], // Consider Google a trusted provider
    }
  },

    google: {
      clientId: process.env.GOOGLE_CLIENT_ID as string,
      clientSecret: process.env.GOOGLE_CLIENT_SECRET as string,
