I want to use app router with nextjs, and I encountered a problem. In order for my application to work, I need to call /api/auth/me to return a user, or null if not logged in. To do this, I need to include an authorization header with the bearer token obtained from localStorage in api.get("/api/auth/me") in axios. I want to do this on the server side because I need my app to display Google ads. How can I do this?

My layout.tsx looks like this

import "./globals.css"; import type { Metadata } from "next"; import { Inter } from "next/font/google"; import Sidebar from "../components/Sidebar"; const inter = Inter({ subsets: ["latin"] }); export const metadata: Metadata = { title: "Create Next App", description: "Generated by create next app", }; export default function RootLayout({ children, }: { children: React.ReactNode; }) { return (    {children}   ); }
