Hello there. I'll make this short. In essence, I am making a custom OAuth system. The user goes to /auth/login, they are then redirected to Google's OAuth portal to sign in, and then they are redirected back to /auth/authCallback, where it takes the code, creates / gets the account, generates a session token, and supposingly sets it. Up until the generation of the session token is something that I have accomplished, but I am failing to find how I'd set the token to the client. If anyone can help, that would be amazing. Here's my code:

// Import \\

import { redirect } from 'next/navigation'
import { Metadata, NextApiResponse } from 'next'
import { authenticateWithOAuth } from '@/lib/dbHandler'

// Export \\

export const metadata: Metadata = {
    title: 'Auth Callback - Top Anime Songs',
    description: 'Auth callback',
}

export default async function ResultsPage({ searchParams }: { searchParams: { [key: string]: string | string[] | undefined }}, req) {

    const code = searchParams.code

    if (code) {
        const sessionToken = await authenticateWithOAuth(code as string)
        // This is where I'd set the session token
    }

    redirect("/")
}
