Why won't Node.js load the favicon?

Question

Node.js

It seems that I am doing everything right, but why then does the server find the favicon, but it is not displayed on the site? What could be wrong? Thanks in advance
Here is the code:

var express = require('express');
var favicon = require('serve-favicon');

module.exports = function() {
    var app = express();
    
    // set engine
    app.set('views', __dirname + '/views');
    app.set('view engine', 'pug');
    
    // headers
    app.use(function (req, res, next) {
        res.header("Access-Control-Allow-Origin", req.headers.origin);
        res.header('Access-Control-Allow-Credentials', 'true');
        res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");
        next();
    });
    
    // static foulder
    app.use(statics(path.join(__dirname, 'public')));
    
    //favicon
    app.use(favicon(path.join(__dirname, 'public/img/assets', 'favicon.ico')));
    
    return app;
}

Perhaps they incorrectly indicated the path in the html itself
. And if I were you, I would delete the line altogether

//favicon
    app.use(favicon(path.join(__dirname, 'public/img/assets', 'favicon.ico')));

Since with these lines you can already refer to the favicon

// static foulder
    app.use(statics(path.join(__dirname, 'public')));
