Validate Client Side Auth On Server

Hi. I have a basic SPA written in react with a client side auth object to handle auth. Now i have other routes on my backend (with the auth server) which are used for different parts of the web app. How can i make sure the user is authenticated on the server for these routes. any help would be appreciated, and sorry if there is a straight forward answer but i couldn't find it. (Unless thats what a server useSession is for??)
Here is the code for the routes in question and the auth logic (taken from the get started docs)
Routes:
app.all("/api/auth/*", toNodeHandler(auth));
app.get("/api/v1/recipe/:videoId", recipeHandler);
app.post("/api/v1/video", downloadHandler)

Auth Logic:
export const dialect = new BunWorkerDialect({
    url: "./sqlite.db",
});
export const auth = betterAuth({
    database: dialect,
    emailAndPassword: {
        enabled: true,
    }
})
Solution
you can use the export auth to make calls like auth.api.getSession that you will pass the original request headers to, here is a NextJS but it will work on any framework (you will need to handle the headers differently based on your framework)

import { auth } from '@/lib/auth';
import { headers } from 'next/headers';

const session = await auth.api.getSession({
  headers: await headers(),
});

if (session) console.log('im logged in');
else console.log('im not logged in');
