Auto-generated file /app/api/shows/route.js

Since this is my first post exuse me anything is not well posed.
What is the file /app/api/shows/route.js for? why auth0 generates it?

This is the content:
import { getAccessToken, withApiAuthRequired } from ‘@auth0/nextjs-auth0’;
import { NextResponse } from ‘next/server’;

export const GET = withApiAuthRequired(async function shows(req) {
try {
const res = new NextResponse();
const { accessToken } = await getAccessToken(req, res, {
scopes: [‘read:shows’]
});
const apiPort = process.env.API_PORT || 3001;
const response = await fetch(http://localhost:${apiPort}/api/shows, {
headers: {
Authorization: Bearer ${accessToken}
}
});
const shows = await response.json();

return NextResponse.json(shows, res);

} catch (error) {
return NextResponse.json({ error: error.message }, { status: error.status || 500 });
}
});

thank you so much
