Sending passport-local and express middleware to express router - node.js

Question

I have a simple app.js file with passport authentication, I have a app.get on my app.js that looks something like this
app.get('/test', isAuthenticated, (req, res) => {
res.json(req.user)
})
When I open this page ('/test'), I get the following data
{
"email": "jhondoe#example.com",
"id": "f8dbee1ba8e95ace16656a008c548b91",
"expiry": "06/10/2022"
}
Now, I'm trying to do the same thing, but in my express router ('/s/main'), this is how I've imported my router
const settings = require('./routes/settings')
app.use("/s", settings)
Now I want to be able to access my 'req.user' and the isAuthenticated middleware that I declared in app.js
function isAuthenticated(req, res, done) {
if (req.user) {
return done();
}
return res.send('You need to be authenticated to view this page.');
}
this is my settings.js file from the routes folder
const express = require('express')
const router = new express.Router();
router.get('/main', (req, res) => {
res.send(req.user)
})
module.exports = router;
Conclusion
I want to do the same thing as the '/test' app.js in my '/s/main' in express router
Thanks for reading
