Call to undefined method "Connect" - laravel

Question

I'm working in a multi-tenant system, I previously tried the https://github.com/hyn/multi- tenant package but in the end I decided to do this implementation with my own method. After a lot of research and testing different things I have managed to build this code, but when I execute it tells me that the connect method is not defined, here I leave what I have done, most likely this is due to some nonsense that I has overlooked, but if someone can help me solve this I would greatly appreciate it
helpers:
use Illuminate\Support\Facades\Config;
use Illuminate\Support\Facades\DB;
use Illuminate\Support\Facades\Schema;
if(! function_exists('conexionBD')){
/**
* Establish a tenant database connection.
*
* #param $hostname
* #param $username
* #param $password
* #param $database
*/
function conexionBD($hostname, $username, $password, $database){
DB::purge('empresa');
Config::set('database.connections.empresa.host', $hostname);
Config::set('database.connections.empresa.database', $database);
Config::set('database.connections.empresa.username', $username);
Config::set('database.connections.empresa.password', $password);
DB::reconnect('empresa');
Schema::connection('empresa')->getConnection()->reconnect();
}
}
Empresa Model:
class empresa extends Model
{
protected $fillable = [
'hostname',
'username',
'password',
'database'
];
public function ciudad() {
return $this->belongsTo('confia\ciudad');
}
public function empresaUsuario() {
return $this->hasMany('confia\empresasUsuario');
}
public function connect()
{
if (! $this->connected()) {
conexionBD(
$this->hostname,
$this->username,
$this->password,
$this->database
);
}
}
/**
* Check if the current tenant connection settings matches the company's database settings.
*
* #return bool
*/
private function connected()
{
$connection = Config::get('database.connections.empresa');
return $connection['username'] == $this->username &&
$connection['password'] == $this->password &&
$connection['database'] == $this->database;
}
}
Middleware Tenant:
use Closure;
use confia\empresa;
class Tenant{
protected $company;
/**
* Tenant Conctructor
* #param empresa $empresa
*/
public function __construct(empresa $empresa)
{
$this->empresa = $empresa;
}
/**
* Handle an incoming request.
*
* #param \Illuminate\Http\Request $request
* #param \Closure $next
* #return mixed
*/
public function handle($request, Closure $next) {
if (($request->session()->get('empresaId')) === null)
return redirect()->route('inicio')->withErrors(['error' => __('Por favor inicie sesión en alguna empresa antes de intentar esta acción')]);
// Get the company object with the id stored in session
$empresa= $this->empresa->find($request->session()->get('empresaId'));
// Connect and place the $company object in the view
$this->connect($empresa);
return $next($request);
}
}
In my session variable empresaId I have stored the ID of my company concat to a static string, this is what gives me the name of the database associated with that company.
When I run the system, at the time of making the change of tenant to start working with another database, I get the following error,
"Call to undefined method app\Http\Middleware\Tenant::connect()"
Someone knows that my code is missing or that I am doing wrong to make the multi-tenant system work correctly?
