How to have databaseHooks event whenever user logs in?

This is my auth code. My goal is to save the date when user logged in.

import { betterAuth } from "better-auth";
import { MongoClient } from "mongodb";
import { mongodbAdapter } from "better-auth/adapters/mongodb";
import { admin } from "better-auth/plugins"
import Logins from "@/models/Logins";


const client = new MongoClient(process.env.MONGO_URI || "");
const db = client.db();
 
export const auth = betterAuth({
  database: mongodbAdapter(db),
  emailAndPassword: {
    enabled: true
  },
  plugins: [
    admin(),
  ],
  user: {
    additionalFields: {
      purchases: {
        type: "string[]",
        defaultValue: [],
      }
    }
  },
  databaseHooks: {
    user: {
      update: {
        after: async (user, ctx) => {
          const id = user.id
          const ip = ctx?.request?.headers.get("x-forwarded-for") || ctx?.request?.headers.get("remote-addr")
          try {
            const newLogin = await Logins.create({
              userId: id,
              ip: ip,
            });
            if (newLogin) {
              console.log("Login saved successfully:", newLogin);
            }

          } catch (error) {
            console.error("Error saving login:", error);

          }
          
        },
      },
    }
  }
});
